Walnut and Buckwheat Sweet Paste

Why people make this paste

Nourilo keeps a stash of thin-shelled walnuts and eats a few each day — they are traditionally valued for the brain and for warming the lungs and easing the bowels. On a cold day a warm bowl of walnut paste is just the thing. Pairing the walnuts with buckwheat — which is rich in minerals like phosphorus, iron and magnesium, plus rutin (rarely found in grains) — makes a comforting dessert that is traditionally associated with supporting the heart and blood vessels.
