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 ↓
Polish Tartlets
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
Roll out the puff paste thin and cut it into 2.5‑inch squares.
Brush each square with egg white.
Fold the corners of each square to meet in the middle and slightly press them together.
Brush the folded squares with egg white and sift sugar over them.
Bake and fill
Bake in a 400°F (200°C) oven for 15 minutes.
Once baked, make a small hole in the center of each tartlet and fill with jam or jelly.

What each ingredient does
- Good puff paste
- Its layered fat and dough puff up in the oven to form flaky, crisp tartlet walls.
- Egg white
- Brushed on before baking, it helps the pastry brown and gives a glossy, crisp finish.
- Sugar
- Sifted on top, it caramelizes in the oven for sweetness and a crisp, golden surface.
- Jam or jelly
- Fills the center after baking, adding sweetness, fruit flavor and moisture.
The step that matters
Brushing the folded squares with egg white and sugar. Sugar needs a thin, even coat of egg white to stick before baking. Too little leaves it bare and pale, and too much can make it burn or stick unevenly.
