1 tablespoon of butter plus more for greasing ramekins
3/4 cup sugar, plus more for dusting ramekins
2 cups fresh raspberries, plus extras for bottom of ramekins
4 eggs, separated
Pinch of cream of tartar
Powdered sugar for garnishing
Preheat oven to 350º. Grease 4 8-ounce ramekins with butter, then dust with sugar. Set 4-5 raspberries in the bottom of each ramekin if desired. Set aside.
Make fruit puree by heating the 2 cups of raspberries, 3/4 cup of sugar and 1 tablespoon of butter in small saucepan. Cook over medium heat, stirring occasionally, for about 10 minutes till sugar is dissolved. Remove from heat, cool slightly, then strain to remove raspberry seeds. Whisk in egg yolks.
In a clean, grease free bowl, beat the egg whites and cream of tartar to soft peaks. Fold one third of whipped whites into the raspberry puree to lighten it. Then gently fold the rest of the whites into the puree. Spoon into prepared ramekins and place ramekins on cookie sheet. Bake in the middle of the oven for about 20 minutes. They should puff over the rim and have a slight jiggle in the center.
Dust with powdered sugar and serve immediately.
