Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
French Butter
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the butter mixture
Pound the suet in a mortar until soft.
Add the butter and salt, and pound until well combined.
Incorporate the egg yolks and work the mixture into a smooth mass.
Use this mixture in the same quantity and manner as butter in puff pastry.
Shape and bake
Roll the crust to ½ inch thick and cut into 2-inch diameter cakes.
Wash the tops with egg and cut a small cross with a sharp knife.
Bake in a moderate oven at 350°F (175°C) until rich brown.

What each ingredient does
- Butter
- Provides fat that melts into layers in the pastry, giving it richness and flavour.
- Egg yolks
- Add richness and emulsify the mixture, helping it bind into a smooth mass.
- Suet
- Adds a firm, hard fat that keeps the mixture stable and adds savoury richness.
The step that matters
Working the mixture to a smooth mass. Pounding the fats until evenly combined keeps them distributed in small pieces, so they form flaky layers when baked rather than greasy patches.
