Shape the shells
Roll out the puff pastry thinly.
Cut out circles with a glass or biscuit cutter.
Cut out the center of two out of three circles with a smaller glass or cup.
Lay the rings on the third circle.
Bake and fill

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Puff pastry
- Its layers of butter puff apart in the oven, forming flaky, crisp shell walls.
- Sugar
- Sweetens the meringue topping and helps stabilize the whipped egg white.
- Egg
- The white whips into a foam that bakes into the meringue topping.
The step that matters
Bake immediately. Puff pastry relies on cold butter creating steam that lifts its layers. If the dough warms and softens before baking, the layers fuse and the shells rise less.
