Martha Stewart_Angel Food Swirl Cake

Bereiding

1. 1

   Preheat oven to 350 degrees, with rack in lower third. Cut parchment to fit bottom of round or heart-shaped 10-inch tube pan with legs or removable bottom. Fit paper into pan. Do not grease pan.

2. 2

   Sift flour, 1/2 cup sugar, and salt together. Sift again into a bowl. Using fork, mash 1/2 cup whole raspberries; strain through a fine sieve to yield about 1/4 cup mashed raspberries.

3. 3

   In the bowl of an electric mixer fitted with the whisk attachment, beat egg whites on medium-low speed until foamy. Beat in cream of tartar and vanilla. Increase speed to medium-high; beat until whites are nearly stiff. Reduce speed to medium-low; beat in the remaining 1 cup sugar, 2 tablespoons at a time. Beat until peaks are almost stiff but not at all dry. Transfer egg whites to large bowl.

4. 4

   Sift flour mixture over egg whites; fold in gently with large rubber spatula. Gently transfer 1/3 of batter to tube pan. Spoon 2 tablespoons mashed berries over egg whites. Spoon another 1/3 of batter into the pan; repeat with remaining mashed berries. Top with remaining batter. Run a knife through mixture, touching bottom of pan, to eliminate any air pockets. Leave the top very textured with peaks in the meringue; do not smooth.

5. 5

   Bake until the top of the cake is lightly golden and the cake springs back when pressed lightly, 35 to 45 minutes. (If top darkens too quickly, tent with foil.)⏱ 45 min

6. 6

   Invert pan onto its legs or hang it over the neck of a bottle or funnel; let cake stand, in the pan, until completely cool, about 1 hour. Run a knife around edges of the cake to loosen the sides. Unmold cake. Serve with buttermilk sorbet and remaining whole raspberries.⏱ 60 min
