Green cardamom pods and fresh ginger root enliven this fruit sauce, made with fresh nectarines. The spices and the cooking impart a tangy, tart flavor to the nectarines. It's great over ice cream or stirred into cooked multi-grain hot cereal and eaten with a splash of cream or soy milk. I created this last summer when I needed to use up some huge ripe nectarines that I purchased at the farmer's market. Substitute about a half a teaspoon of ground cardamom if you don't have the whole green pods.
