Before primitive man began cultivating his food, he relied on foraging in the wild.
In the warm months, there were plenty of fresh fruits, berries, shoots and greens for Woodland Indians to eat, but these would be gone with the first hard frost. To get through the cold months, he relied on nuts, tubers, and roots that could be gathered in autumn and stored in pits. In the Northeast, storage pits were essentially large holes dug out of the earth that were lined and covered with bark.
Unfortunately for the North American Indians, the earth's offerings of tubers were slim in comparison to their contemporaries in the more temperate southern hemisphere. South America boasts the richest natural diversity of edible tuberous species— the most important being potatoes (Solanum tuberosum), sweet potatoes (Ipomoea batatas), and cassava (Manihot esculenta).
To the east, Eurasia, which includes the Mediterranean Basin and Pacific Islands, also possesses a large diversity of indigenous tuberous plants and some of the first brought into cultivation. Among these are taro (Colocasia sp.), yams (Dioscorea sp.), and the proliferate kudzu (Pueraria lobata).
In North America, the introduction of the potato and sweet potato appropriated the domestication of our own native tubers. The two most prized by Woodland Indians— groundnut (Apios americana) and arrowhead (Sagittaria latifolia)— have never been widely cultivated. Today, there is only one tuber indigenous to the United States that holds a place in the world's common stock of vegetables: the Jerusalem artichoke, or sunchoke.
The sunchoke (Helianthus tuberosis) is the tuber of a species of sunflower that can grow up to ten feet in height. The French explorers were so smitten by the flavor of the cooked tubers that they sent specimens back to France, where it began to be cultivated. The Italians, who thought that it tasted like artichokes, labeled it girasol articiocco (sunflower artichoke) and planted it in the famous Farnese gardens. The English, who were also cultivating the tuber, mispronounced the Italian label, calling it Jerusalem artichoke and the name stuck. It's interesting that a plant that was introduced to the Europeans by the Native Americans was enjoyed abroad for over three hundred years, and until recently has been largely ignored, or used for cattle feed, in it's native country.
Onions are thought to have originated in central Asia, though it's likely that many countries had their own wild species that became domesticated simultaneously. In North America, we have Allium canadense (pictured above) and ramps, or wild leeks (Allium tricoccum). These were foraged by Native Americans and used to enhance the flavor of vegetables and meat.
Common burdock (Arctium minus) is the taproot of a biennial thistle. Native to Eurasia, it was introduced to North America by the early European settlers and quickly adopted by the Native Americans as food and medicine. Because it contains many phytochemicals, it was used for a wide range of ailments from rheumatism to skin acne. Today, it is being studied for its anti-cancer properties.
Burdock was an important winter food for Native Americans, who dug up the the roots in the fall and dried them for winter use. Fresh roots have a sweet, nutty flavor, punctuated by a deep earthiness that is off-putting to some. The skin looks thick and tough, but is actually quite thin. The flesh is milky white, but quickly oxidizes and must be immediately submerged in cold water to prevent it from turning brown. Older roots are fibrous and must be cooked; the young roots are tender and crisp when raw, but should be thinly shredded and soaked in several changes of salted water to extract some of the pungent earthiness.
In autumn, the seed heads (above, left) are covered with fine spurs that easily attach themselves to clothing. In the 1940's, this characteristic captured the attention of George de Mistral, who went on to use it as a prototype for a hook-and-loop fastening tape that he invented. We know it as velcro.
Goldenrod (Solidago) is a native wildflower belonging to the plant family Asterceae. Other edible members of this family include: sunchoke, burdock, artichoke, chicory, and lettuce. Although it is sometimes regarded as evasive because of its ability to adapt and dominate, it is also widely cultivated for its profuse yellow blooms. In the wild parts of my yard, the goldenrod grows alongside the burdock and make amiable companions in the landscape as well as the palate.
Native Americans dried goldenrod leaves to flavor teas and broth. They also cooked the leaves and ate them as greens. Goldenrod produces pollen that is collected by bees to make a strongly-flavored honey. I find the flowers and pollen tastes like carrots and parsley, with a hint of mint.
An interesting characteristic of goldenrod is its natural rubber content. Thomas Edison experimented with this property and produced a rubber that is resilient and long lasting, but was preempted by synthetic rubber. The tires of his Model T (given to him by his friend Henry Ford) were made of rubber from his experiments.
One of the most daunting aspects of cooking "native" is the lack of dairy. Before the introduction and domestication of cattle, there was no widespread use of animal milk, therefore no cream, butter, or cheese to enrichen foods and carry flavors. For this, the Native Americans relied on nuts.
Nuts and seeds were an important staple in the Indian diet and their gathering was part of an annual cycle of activities. Nutmeats were laboriously pounded in stone mortars; the resulting pastes were used like butter in cooking and baking, or dried and used as flour. Nut oils were extracted by mixing water with the paste and skimming the separated oil that rose to the surface. The remaining paste was further diluted and used as milk.
Another food missing from the native diet is vinegar. Aside from fermented corn mash that was introduced to southwestern tribes (via central and south american influence), fermentation of plant liquids was not widely practiced by North American Indians. This seems incongruous with the ancient history of fermented beverages by the rest of the world, but explains why today's Native American population has a high percentage of alcohol intolerance. Similarly, the void of dairy products also accounts for lactose intolerance among 95% of the same population.
Earth Salad
burdock, sunchoke, wild onion, hazelnut, goldenrod
I've dressed this salad with nut butter to show the versatility of the native staple. I chose hazelnuts because of their affinity to the artichoke— a relative of the burdock, sunchoke, and goldenrod. To my modern sensibility, it proved to be one-dimensional in taste and lacking the counterpoint of acidity. Although I'm striving for authenticity of ingredients, I did not hesitate to add cider vinegar in the interest of flavor balance. Nor do I apologize for using my high-speed blender. After all, I live in the New World where the convenience of electricity and technology makes cooking more efficient, and, by contrast, makes this exercise all the more poignant.
