Brassica/Sinapis — the wild mustard that came up volunteer in fallow rows, gathered free and cooked down exactly like the garden mustard greens it gave rise to. Sharp, mustardy, and full of cold-weather nutrition.
Cultivated mustard greens are a cornerstone of the Sunday soul-food table; the wild plant is the reminder that the seed came from the field first. Families who couldn't buy seed or had no garden plot gathered the volunteer wild stands and cooked them the same way, keeping the green on the table and the knowledge in the line.
Wild mustard greens carry the same dense vitamin A, C, and K profile as their cultivated descendants, plus the glucosinolate-derived isothiocyanates studied for liver detoxification enzyme induction and anti-cancer activity. The young leaves were a free, vitamin-rich green; the seeds are the source of mustard, used traditionally as a warming poultice for chest congestion (the classic mustard plaster).
Gather young, tender leaves before the plant bolts into yellow flower. Cook down like any pot of greens — boiled with smoked meat or quick-sautéed. The seeds can be gathered, dried, and ground for mustard or used in a hot mustard-seed poultice on the chest for colds.
