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 ↓
Hazel-nut Macaroons
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Pound the hazelnut kernels in a mortar until they form a paste.
Gradually add the egg whites, stirring to combine.
Stir in the castor sugar and mix until smooth.
Shape and bake
Arrange the mixture in rounds on wafer paper.
Bake in a moderate oven (350°F / 175°C) for about 30 minutes.

What each ingredient does
- Hazelnut kernels
- Provide the main nutty flavour and the oily, paste-forming base of the macaroons.
- Egg whites
- Bind the paste and help the macaroons hold their shape and set when baked.
- Castor sugar
- Sweetens the macaroons and helps them dry to a crisp, lightly browned surface.
The step that matters
Adding the egg whites gradually. Adding the whites slowly and stirring well lets them blend evenly into the nut paste without deflating or loosening it too much, so the rounds keep their shape in the oven.
