Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Tart Shells
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the shells
Roll out the pastry thinly and cut circles with a glass or biscuit cutter.
Use a smaller cutter to remove the centers of two out of three circles.
Place the rings on the third circle to form a wall around the shell.
Bake on a baking pan in a 400°F (200°C) oven until golden.
Fill and brown
Once cooled, fill the shells with jelly.
Beat the egg whites to stiff peaks, then add sugar and spread over the jelly.
Return the shells to the oven and brown the meringue delicately.

What each ingredient does
- Plain or puff pastry
- Forms the crisp, sturdy shell that holds the filling.
- Jelly
- Provides sweetness and a glossy, set layer inside the shell.
- Egg whites
- Whipped with sugar, they form a light meringue topping that browns in the oven.
- Sugar
- Sweetens the meringue and helps it hold its structure and brown.
The step that matters
Beating the egg whites to stiff peaks. Egg whites must be whipped until firm so the meringue holds its shape and bakes light rather than collapsing or weeping. Any trace of fat or yolk in the bowl can stop them from whipping properly.
