Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

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
Preheat the oven to 400°F (200°C).
In a bowl, beat the eggs with the sugar until light and fluffy.
Sift the flour and mix it with the cream of tartar.
Dissolve the baking soda in a little water and add it to the mixture.
Flavor with lemon or vanilla.
Bake and serve
Drop spoonfuls of the batter onto buttered baking sheets.
Bake in the preheated oven until golden.
Serve with ice cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped with sugar to trap air, giving the drops a light, fluffy structure.
- Sugar
- Sweetens the batter and helps the eggs hold their whipped foam.
- Sifted flour
- Provides the starch that sets during baking, giving the drops their body.
- Cream of tartar
- Acidifies the batter, stabilizing the egg foam and helping the drops keep their shape.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the drops rise.
The step that matters
Adding the baking soda. Baking soda starts releasing gas as soon as it meets the acid, so the batter should be baked promptly after it is dissolved and mixed in. Waiting lets the lift fade and leaves the drops flatter.
