Elderberry

Elderberries are the small, intensely flavored fruit of the elder shrub (Sambucus nigra in Europe, S. canadensis in North America), growing 4–6 mm in diameter and ripening to a deep purple-black in late summer. Their flavor is tart with a subtle floral undertone—more acidic and assertive than blackberries—and their high natural pectin makes them exceptional for setting jams and preserves without added thickeners. The berries grow in clusters called umbels, typically yielding 2–3 cups of cleaned fruit per pound of whole clusters. Historically one of the most widely foraged wild fruits in temperate regions, elderberries have been used since antiquity for cordials, wines, and medicinal preparations; the Anglo-Saxon name "æld" (fire) refers to hollow elder stems used to stoke flames. All parts of the raw plant—berries, bark, stems, and leaves—contain cyanogenic glycosides and must be cooked before consumption, but properly prepared berries are remarkably versatile. The European elder has been cultivated for centuries and remains prized for wine and cordials, while American elderberry is preferred for preserves and is more cold-hardy. Foragers must distinguish the edible black elderberries from the toxic red-berried elder (Sambucus racemosa), which grows throughout North America and Europe and causes severe gastrointestinal distress; the distinguishing feature is cluster shape (flat umbels versus pyramidal clusters) and leaf texture, but beginners should avoid red-berried elders entirely.
