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 very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs and sugar until frothy.
Stir in the flour, cream of tartar, and baking soda until well combined.
Add lemon flavoring to taste.
Bake and serve
Butter baking sheets and drop the mixture by teaspoonfuls, spacing them about 3 inches apart.
Bake immediately in a very hot oven at 400°F (200°C), watching closely to prevent burning.
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, they trap air that gives the drops their light, airy structure.
- Flour
- Provides the structure that sets the drops as they bake.
- Cream of tartar
- Acidifies the batter and stabilizes the foam, helping the drops hold their shape and stay tender.
- Baking soda
- Reacts with the acidic cream of tartar to release gas, helping the drops rise.
- Sugar
- Sweetens the drops and helps stabilize the whipped eggs, adding tenderness and browning.
The step that matters
Bake immediately in a very hot oven. The batter's leavening starts reacting as soon as it is mixed, and the air trapped in the whipped eggs can slowly escape. Baking right away at high heat sets the drops quickly, so they rise well and do not spread or burn before they set.

Fit is the average pairing score against egg, sugar, flour, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
