Picture iceberg lettuce– the kind you find in a pile in your local produce department. Everybody knows what it looks like and how it tastes, how the outer leaves tend towards the soft and green, and how the inner leaves are crunchy and sometimes sweeter. Whether cut into wedges and drizzled with Blue Cheese dressing, shredded in a machine and tossed into a taco, or layered on a burger or sandwich, the lettuce you grow in your garden or buy in the supermarket will consistently share these characteristics. Iceberg lettuce (Lactuca sativa), and its domesticated cousins like Romaine, share the consistency of cultivation. Through thousands of years of breeding, we can now fairly regularly assume that the iceberg lettuce we buy at the market will have the same flavor profile as the iceberg lettuce we order at a restaurant.
This tends to be true for most cultivated vegetables. A tomato will taste ‘tomato-y,’ and one variety of apple will taste similar to other examples of that variety, pretty much across the board. Cultivation allows us to control the qualities of these plants (although when we breed for one quality like color or shelf life, we often lose on other attributes like flavor). Wild greens, however, are a different story entirely. Plants in the wild, impacted by a spectrum of influences and growing conditions, can vary in flavor, size, and color, sometimes significantly.
This can pose a problem for the home cook. If a recipe calls for, for example, a cup of chopped dandelion greens, and the cup of greens you happened to find the day prior were growing in full sun and relatively mature, they’re going to be far more bitter than you may like, and will impact the recipe accordingly. For this reason, most recipes including wild ingredients should include “to taste” far more often than they do.
Wild lettuce (Lactuca serriola) – Picture by Author
Wild lettuce (Lactuca spp.), for instance—the common ancestor of all of our cultivated lettuces, can thrive in a number of conditions, all of which will influence its flavor. Most wild lettuces, members of the Asteraceae family, have an intensely bitter flavor profile. However, the experienced finder will occasionally stumble across an example that is mild and sweet. Consider: if no wild lettuces were ever mild and sweet, we would never have been able to breed these qualities into our domestic varieties! If one is lucky enough to have stumbled across a sweet instance of Wild Lettuce without ever having tasted a bitter example, one is in serious danger of serving a particularly intense wild salad the next time.
Foraging groups online are full of debates on what the “true flavor” of wild edibles really is. Salal (Gaultheria shallon) is an excellent example. This Pacific Northwest understory shrub has edible berries. Those individuals who harvest salal from shaded areas report that the berries are “insipid” and good for no more than a trailside snack. Those collected from bushes growing in full sun, however, insist that salal berries are actually sweet and juicy and good for jams and pies. They’re BOTH right, of course! It’s just that the growing conditions of each individual salal bush will determine the flavor profile of its berries.
Seasonality is another good example. Getting to know a wild plant means learning about how it manifests in all of the seasons. Something that can be used one way during one part of the year might be used differently earlier or later. This kind of deep, seasonal exploration allows us to interact with our plant companions on many levels. Someone who tastes a dandelion mid-summer may have an entirely different experience than someone who tastes the first dandelion greens of spring.
Really, the only 100% way to know how a wild plant will perform in a recipe is to taste each single instance. It follows, however, that the experienced forager will learn to determine what to collect based on her individual needs. Someone attempting a recipe for a sweet dessert made from salal berries should pick some from a bush growing in the sun, not from a bush growing trailside in a shady conifer forest.
The upshot? Taste as you go, let your palate guide your harvest, and learn flavor profiles of plants by family. Need bitterness for balance? Reach for wild lettuce rather than bland iceberg. Chasing sweetness for salal jam? Seek out bushes basking in full sun, not those lurking in the cool hush of conifers. When you meet a plant on its own terms—in its own place and season—you trade the supermarket’s certainty for something richer: a living dialogue of flavor between you and the wild.
