Gingko nut by John Spottiswood.

These nuts date back some 150 million years, and are believe to be a powerful aphrodisiac. Asian cooks like to use them in desserts and stir-fries. They're available in Asian markets either fresh (in the fall), canned, or dried. To prepare fresh nuts, crack open their shells and then pour boiling water over the nutmeats. Let them soak for about ten minutes until their skins are loose. Peel off the skins, then put the nutmeats in a pot full of boiling water, let it simmer for about thirty minutes, then drain. Canned nuts have already been shelled, skinned and boiled, but they're mealier than fresh nuts. Rinse them before using.
