Our most requested celebration cake is also one of the simplest: light vanilla sponge, barely-sweet mascarpone cream and a tumble of berries macerated just long enough to turn jammy at the edges. Elena developed it for a student's wedding and has taught it every summer since.

The secret is restraint — whip the cream to soft peaks so it slices cleanly, and salt the berries. A pinch of salt makes raspberries taste more like themselves.
