Red Russian kale — tender, flat oak-leaf-shaped leaves with purple stems. The most delicate of the kales, good raw or quickly cooked, easy on the digestion.
A favorite of Southern home gardeners and CSA boxes because it overwinters and stays tender. It introduces greens to people who find collards and curly kale too tough or bitter.
Red Russian kale carries the cruciferous glucosinolate-to-sulforaphane pathway for cancer protection and estrogen metabolism, plus dietary nitrate for nitric-oxide blood pressure control. Its purple veins signal anthocyanins — the same anti-inflammatory pigments in muscadines and hibiscus — that support blood vessel health. Because the leaf is tender it can be eaten raw, preserving the full vitamin C, folate, and glucosinolate load that long cooking degrades.
Tender enough to eat raw after a quick massage with oil and acid, or to wilt in 2-3 minutes. Strip the thin rib only if very mature. Cooks far faster than curly or dinosaur kale.
