Cheesecake Cloud with Berries

Combine crumbs and melted butter. Pat evenly over bottom of an 8-inch cheesecake pan (at least 3 1/2 in. deep) with removable rim.

Bake in a 325 oven until crust is slightly browner, about 15 minutes.

Meanwhile, with a mixer on high speed, beat the 4 egg whites and cream of tartar in a large bowl until foamy. Gradually add 1/2 cup sugar, about 1 tablespoon at a time, beating until the whites hold stiff, shiny peaks.

In another large bowl, stir remaining sugar with cornstarch, then add egg yolks, cheese, lemon peel, and vanilla. Beat (with unwashed beaters) until well blended.

Fold beaten whites into cheese mixture. Scrape the batter into hot or cool crust.

Bake in a 325 oven until center barely jiggles when cake is gently shaken, 50 to 60 minutes. Run a thin-bladed knife between cake and pan rim. Refrigerate cake, uncovered, until cool, at least 3 hours. (If making ahead, cover when cool and chill up to 1 day.)

Melt jelly (in a microwave oven or in a small pan over medium heat), stirring often. Cool, stirring occasionally, until jelly becomes a thick syrup, about 5 minutes.

Remove pan rim. Mound berries on cake and drizzle with jelly. To neatly cut this fluffy dessert, hold a long strand of string (such as dental floss) taut, slide it under the berries to the center of the cake, and push the string down to the pan. Slide out string and repeat to cut wedges. (If using a knife, wipe blade clean between cuts.) Slide a pie server under each wedge and lift out gently.
