This recipe calls for roasting strawberries, but you can roast any fruit you like. Roasting fruit prior to using it in ice cream or frozen yogurt allows the fruit flavor to deepen. Roasting allows the fruit to better incorporate into the final product. Tossing in sliced raw fruit can lead to hard, icy chunks and the flavor does not distribute through out the ice cream/frozen yogurt. Once you’ve roasted fruit for your ice creams or frozen yogurt, you’ll never consider raw fruit again.
