Why it works: Sugar and egg 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 ↓
Sugar Icing for Tarts
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the tart
Line the edges of a tart dish with good crust.
Fill the crust with fruit and sprinkle with sugar.
Cover with a crust.
Press down the edges of the crust.
Trim the edges neatly.
Make small holes on each side for steam to escape.
Glaze and bake
Brush the tart with cold water.
Sift sugar thickly on top.
Brush the tart with whisked egg white.
Sift sugar on the egg white before baking.
Sprinkle a little water on top.
Cover with paper if needed.
Bake in a 350°F (175°C) oven for about 30 minutes.

What each ingredient does
- Good crust
- Forms the case and top that enclose the fruit while it cooks.
- Fruit
- Supplies the filling and moisture that bakes inside the tart.
- Sugar
- Sweetens the filling and, sifted on top, helps the surface brown.
- 1 egg white
- Brushed on the top, it helps the sugar stick and gives a glossy, crisp finish.
The step that matters
Make small holes on each side for steam to escape.. Steam from the fruit must have an exit, or pressure can build under the top crust and split it open while baking.
