How to Cook a Weed

We exist at a turning point. Our world has changed dramatically since the last millennium, but no century has been so dauntingly transformative as the last. Not only is our climate changing rapidly, not only is a great extinction underway (perhaps the greatest, perhaps the last), but we have finally become aware of the endpoint of our resources, and the limit of our invention. It is not enough anymore to keep the machine in motion. We need to apply some brakes. We need to remember how we got here. It is not enough to stop using straws, or bring canvas bags to the supermarket. We need a massive rethink in terms of how we interact with our environment, and food is at the forefront of that interaction.

I am intending to present not a manual for that rethink but a simple volley in the effort, a salvo lobbed at the ceaseless farce of endless growth. There is no permanent economic growth that will not reduce this planet to a sobbing, shrieking wretch. And not for the benefit of the faceless masses, but for the gain of a very few at the expense of the very many.

Most corrupted and most casually ignored are our food systems (clothing also comes into this, but the stakes are higher economically and that is not the subject of this volume). We are not the architects of this, but the unwilling participants–20th century consumption made us acclimated to food in plastic wrap, ingredients as commodities, food severed precisely and sharply from its source. Meat isn’t animals, it is flesh drained of blood and wrapped in styrofoam packages. Vegetables aren’t plants they are Californian-grown produce, shipped across the country in massive Diesel vehicles. Plants come in cans, in plastic freezer bags, in joyless shrink and sleeves. We have lost the thread connecting us to our food.

Just a few generations ago, most of our grandparents and great-grandparents existed in a transitional world. Industrial growth and technology impacted their lives massively, but attached to that incredible change was a sense of connection with another world. The world of self-sustenance, of the working and (dare I say it) peasant classes which revealed to them a set of knowledge and tools which connected them much more tangibly to their food sources. Of course, this is a generalization, and largely a class based one. After all, landowners in the Middle Ages were just as severed from the source of their heavily-laden feast tables as modern oligarchs. The difference is that now this disassociation effects almost everyone in the developed world.

My grandmother raised four children by herself, and supplemented their diet with wild foods. But this connection to the folkways of wild food did not descend directly to me. Although my mother did show me that the invasive wineberry was edible, and I happily munched on honeysuckles as a child, this knowledge was not inherited. I became interested in wild food as an outgrowth of cooking, and an interest in ecology and sustainable lifestyles. Most of what I have come by has been self-taught, aided by print and internet resources, as well as experimentation (within the margins of safety of course). I say this mainly to demonstrate that no matter how far you might be disconnected from the world of the food knowledge and skills of your ancestors, it is a connection you can re-establish. It doesn’t take a lifetime, either–just an interest and the right resources. I aim for this site to be one of those resources, and to guide you to many others.

Along the way I also want to change the way you think about food sources, the environment, cooking and life. My goal is not to provide you with an encyclopedic overview of every wild food but some of the most essential, most common, and most widespread across the temperate parts of the world. The cooking techniques and recipes included in this site are fundamentals, simple presentations, what is known in Italian as cucina povera, the cooking of the poor. A few things may seem complex or challenging at first, but I promise that with practice many of the more involved or unfamiliar processes (like fermentation) will become second nature. All of these techniques formed part of the daily cuisine of the nonnas and farmhouse wives that nourished many generations of our ancestors. And I promise you that, whether your tradition is European, or Indian, or Japanese, or anything else, these women incorporated wild foods into their cooking. Mainly out of necessity, but also out of knowledge of their nutritional aspects, medicinal benefits, and flavor.

As our world transforms dramatically, it might be some small comfort to realize that we can rediscover this knowledge, and explore new ways of sustaining ourselves that are less impactful and far more healthy than the supermarket cooking we have all become used to. One advantage of how aggressively our agriculture and industry have transformed the landscape is that it creates the perfect environment for adaptive, vigorous, invasive plants which are the fundament of wild cuisine. These are the so-called weeds, neglected and often despised. If we can learn to honor and celebrate them, if we can learn how to cook a weed and cherish the food we can make from them, we will not only reconnect with our not-so-distant past but create a path which can help minimize the damage we do to this planet every day with our current foodways.

I hope you will join me in discovering how exciting, delicious, and mindful this food can be.

Wild & Conventional Herbs Preserved in Salt

IMG_0048.jpg
Picking lovely field garlic in mid-winter to add to herbs preserved in salt.

The harvest and use of herbs and greens is a year-round process in my kitchen. Generally, I use wild herbs and seasonings or those grown in my garden, but of course many fine farms and friends grow herbs as well, so there is plenty of bounty to preserve, even in the off-season. I am always looking to explore ways to keep the ingredients seasonal, but extend their life by various preservation methods, so that I can have my cilantro in winter and not feel too guilty about it. One of the best ways to do this is to employ a bit of salt. Indeed, quite a bit of salt. By chopping fresh herbs (augmented if you desire with a little vegetable material such as leek, celery or carrot) and combining with salt you can keep some of the bright intensity of fresh aromatics from decaying.

Our culinary herbs, especially those that dominate the cooking of the Mediterranean basin, are nearly all drawn from two plant families. The majority of plants that most cooks from that tradition (and indeed, many others) will recognize as herbs are either a member of the Lamiaceae (Mint Family) or Apiaceae (Carrot Family). The first includes the obvious “true” mints such as spearmint and peppermint, but also widely-used seasonings such as thyme, oregano, rosemary, basil, shiso, savory, lavender, etc. The second contains cilantro and parsely, alongside dill, fennel, caraway, chervil, anise, angelica, and many more. In addition to aromatic herbs, the carrot family has a number of vegetables (celery, carrot, parsnip, fennel) and plants whose seeds are used as spices (cumin, coriander, ajwain, caraway, alexanders). It might come as no surprise that a number of the wild plants we can use as herbs also come from these same families.

There are a number of methods available to preserve the flavor of fresh herbs when they are in season. The one most people will be familiar with is drying, I have found this to be a particularly excellent method to use when dealing with the mint family. Indeed, many of the mints which we collect as wild plants or grow have a marked flavor improvement when dried. Oregano, for instance, or the plant Monarda fistulosa (Wild Bergamot) are herbs I don’t use great amounts of fresh, finding them a bit too intense for most things. However, when dried they are huge staples of my kitchen year-round. But while dehydration is effective for the mints, it tends to make the more subtle flavors of the carrot family disappear. Anyone who has used dried parsley will discover pretty quickly that it tastes precisely like nothing. Again, this extends to the wild members of the family–my attempts to dry pushki (Heracleum maximum) leaves without treating them first has invariably resulted in a tasteless product. Drying of aromatic members of the genus Allium (Onions, Chives, Leeks, etc) is also sometimes fraught with difficulty. Leek greens hold up fairly well, and sometimes chives, but the wild members tend to lose their more ephemeral flavors.

My preferred methods to preserve both Alliums and Apiaceae are to use brine or vinegar, infusion or lacto-fermentation, and very occasionally freezing. But the best technique is the one detailed here. What you are creating will be high enough in salt that it becomes a substitute for that when used in a dish. In much the same way that one would use a seasoned salt, or a curry paste, or a pickled or fermented ingredient high in salt, you will want to taste your dish before adding any additional salt or salty ingredients like soy sauce to it. But a small amount of herbs preserved in salt can be used as the base for a vinaigrette or soup, added to a sauce, stirred in with dressing for a composed salad, added to the salt bill for curing meat or fish, stirred into a pasta with a bit of the cooking water, or used as the basis for a fresh salsa. Of course one could get even more creative than this, and luckily there will be plenty of time to–my herbs in salt mixes tend to last at least one year, some may linger even longer.

The recipe I use originated in a book called The Mediterranean Pantry by Aglaia Kremezi, and she uses US/Imperial measurements, always at a ratio of 6 ounces of vegetables for every 1.25 ounces of salt. This works out at a ratio of 4.8:1. For more precise measurement, I tend to use grams, and simplify the ratio to 5:1, but of course you can do as fits your kitchen and scale best. No matter what vegetable and herb components are used, however, the ratio should stay the same. This makes for 20% salinity, which means these herbs will likely stay fresh a lot longer than you. It is quite likely that a lower salinity would work fairly well too, but I tend to stick with this recipe as the color and taste stay so bright and fresh that I simply use the herbs as a salt substitute, and especially when added as the base for soups or stews the intensity of flavor is such that I feel I end up actually using less salt in the long run.

Absolutely any combination of herbs and vegetables is viable and I encourage you to experiment widely with this recipe, but I’ve included a few different iterations of it just as basic models. I always use a fine sea or other natural salt for this, such as Himalayan pink salt. Never use industrial salts like iodized table salt or kosher salt, and never use large crystals or rock salt unless you grind them first. Do not make the mistake either of combining the salt and the herbs and then processing, or you will wind up with more of a slurry than a condiment. In all cases, pack the herbs in salt well into 4 or 8 oz jelly jars (each recipe makes two of the former or one of the latter) and keep refrigerated. Should last at least one year, and often longer. Make sure that you integrate the salt well into the chopped herbs, tossing in a bowl several times before packing into the jars.

herbs combined with salt, ready to pack into jars

Bittercress, Dandelion & Field Garlic

I make this in spring when all three herbs are at their finest and I can collect them from my yard. This combination of herbs also makes an excellent base for pesto. Make sure that you use a food processor if using field garlic, and that you snip it very fine first as it is quite fibrous. The same can be said of chives

chop extremely fine by hand or pulse in a food processor:

100 g bittercress (Cardamine species)

60 g dandelion greens

40 g field garlic greens or chives

mix in:

40 g fine sea or other natural salt

Waterpepper & Shiso

The sharp intensity of waterpepper (one of the flavorful smartweeds will work too) is balanced by the distinctive herbaceous flavor of shiso. Both grow abundantly in my area as invasives, and I make this in mid-summer before both plants begin to flower.

chop extremely fine by hand or pulse in a food processor:

80 g shiso (Perilla frutascens) or thai basil

80 g waterpepper (Persicaria hydropiper), smartweed or rau ram (Vietnamese coriander)

40 g field garlic bulbils or leeks

mix in:

40 g fine sea or other natural salt

Mock Strawberry : A Disdained Common Edible

IMG_9515

As a child I used to gobble the “wild strawberries” that, then as now, popped up in our lawn and mulched beds alike. Sure, they didn’t taste like much but they were a pleasant nibble. Perhaps more caution was in order, but the darned things are so inoffensive looking that it would be difficult to suspect them of being hazardous. Older and slightly wiser, nowadays I don’t tend to eat anything without being quite careful about it. In the grocery store, one examines a package. In the wild or the backyard, one makes sure to clearly identify a plant before consuming it.

These wild “strawberries” were of course not true wild strawberries (which are far from flavorless) but the invasive, pernicious ground cover known as Potentilla indica or Duchesnea indica. The confusion over classification is a recent one and Duchesnea is still mainly used. Potentilla seems to be the more accurate fit (though I am hardly a botanist), since that genus contains the cinquefoils whose leaves are used in very much the same way as those of mock strawberry.

Leaves? That’s right. For years and years I have eaten the charmingly inoffensive fruit of the mock strawberry without realizing that the far more interesting and useful part of the plant was staring me in the face. The leaves are an excellent food and tea, tasting faintly of cucumber (with a hint of sage) and widely available for almost the entire year. For years I have let this plant grow wild in my yard and planted beds for the simple fact that it is harmless and excludes other, non-useful weeds. Now? I will definitely encourage its’ growth and use it whenever necessary. Which, honestly could be often–the only plant that grows more prolifically in my yard in the off-season is ground ivy, equally edible but quite bitter once springtime has ended.

So what about those fruits? Many find them banal or insipid, but I consider that a judgement based more on its flavor in comparison with other wild berries or with commercially cultivated fruit. Another common observation is that they taste like watermelon bitten very close to the rind. That rings true to me, and also implies the thing I do really like about mock strawberry, which is its’ pleasing texture. Too often we are disdainful of things which have mild or inoffensive tastes. I have a feeling we would be less disdainful if we did not have such a surplus of food. Then we might be quite pleased to have a plant which is edible in the Northeast in one form or another for almost the entire year.

When we forage we learn a lot of lessons about plants and our relationship with them. Mock strawberry is a good example : as much as we might despise this little scrubby ground cover, we can potentially (no pun intended) learn from it and its’ ways. Sometimes the best and most useful plants are those which we most ignore. I have always tolerated and sometimes enjoyed mock strawberry as an invasive plant which excluded far more annoying weeds. Now I just might let it run riot, and delight in the free surplus of winter greens and summer berries. Insipid? Maybe. But when you’re starving don’t come over and scoop up my “mock” strawberries. I’ll still be enjoying them, tasteless or not.
