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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Roll out the puff pastry until very thin and cut into squares slightly larger than 2 inches.
Moisten the surface of each square with a little water and fold the corners to meet in the center.
Place a small ball of pastry in the center of each folded square and press it down lightly.
Bake and serve
Brush the tartlets with the beaten egg and sprinkle with powdered sugar.
Bake in a hot oven at 400°F (200°C) for 15 minutes.
Before serving, add a little bright-colored jam around the pastry ball and serve on a neatly folded napkin.

What each ingredient does
- Puff pastry
- Forms the flaky, layered shell that puffs and crisps when baked.
- Egg
- Brushed on the surface to promote browning and a glossy finish.
- Powdered sugar
- Sprinkled on top to add sweetness and a light surface finish.
- Jam
- Adds sweetness, fruit flavor and bright color beside the baked pastry.
The step that matters
Brushing with egg and sprinkling sugar. Egg brushed evenly gives uniform browning and gloss, while sugar caramelizes in the oven. Uneven coverage leads to patchy colour or burnt spots, so brush before the sugar is added and avoid pooling.
