This blancmange is pure white, wonderfully airy and richly flavored with almonds. It’s firm enough to unmold, but still creamy. Make this in ½-cup ramekins or other individual molds, unmold and serve, surrounded with fresh fruit. The fruit should be a little tart to cut the richness of the almonds and cream: A combination of sliced peaches, raspberries and a few blackberries or blueberries is ideal
