Why it works: Egg and butter 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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the moulds
Prepare the batter as directed in the previous recipe.
Grease small oblong-shaped moulds with clarified butter and drain excess grease.
Coat the interiors of the moulds with fine sifted sugar.
Bake
Fill the moulds with the batter and sprinkle fine sugar on top.
Bake in a moderate oven at 350°F (175°C) for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Trap air when whisked, giving the sponge its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilise the whisked egg foam.
- Clarified butter
- Greases the moulds so the cakes release cleanly and brown lightly.
The step that matters
Fill the moulds with the batter and sprinkle fine sugar on top.. Overfilling or leaving the batter standing too long can deflate the whisked egg foam, so the cakes may bake flat and dense.
