Foraged black walnuts cracked from their hull in fall. A ritual. Intensely flavored, far beyond English walnuts. Ancestral brain food.
In Black Appalachian and Southern communities, the fall black walnut harvest was a family event. The whole family participated in hulling, drying, cracking, and picking the walnut meat — a process that stained everyone's hands dark for weeks. The harvested walnut meat went into cakes, pies, and breads for the fall and winter season. Black grandmothers made black walnut pound cake and black walnut fudge as holiday foods. The labor of cracking was communal; the reward was profoundly flavored.
Black walnuts contain significantly higher concentrations of omega-3 ALA, ellagitannins, and juglone than English walnuts — the polyphenol profile is more potent. Ellagitannins convert to urolithin A in the gut, which has documented anti-inflammatory and potential anti-cancer effects. Melatonin content is among the highest of any food. Magnesium and potassium together address the two most common deficiencies in hypertensive Black Americans. The omega-3 ALA supports cardiovascular and cognitive health.
Harvest black walnuts in September-October when the green hull begins to blacken. Wear rubber gloves — the hull stains skin and clothing permanently with juglone. Hull the nuts by driving over them on a driveway or using a hulling board. Allow the shelled nuts to dry and cure in a single layer for 2-4 weeks in a well-ventilated space. Crack with a specialized cracker or a hammer and anvil method on a concrete surface. Pick the meat from the shell with a dental pick. The effort is enormous; the flavor is worth it.
