Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Delicate Cup Cake

Oven, in the book's wordsA moderately quick oven

Ingredients

Directions

The book says “a moderately quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a bowl, beat the egg yolk, sugar, and cold cream until foamy.

  2. Add grated lemon rind for flavor.

  3. Gradually stir in the flour while beating briskly.

  4. Gently fold in the beaten egg whites until just mixed.

Bake

  1. Pour the batter into oiled gem irons.

  2. Bake in the preheated oven until light and delicate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Whipped and folded in, they trap air that lightens the batter and gives a delicate crumb.
Flour
Provides the structure that holds the batter's shape as it bakes.
Cold cream
Adds fat and moisture, giving the cupcake a tender, rich texture.
Egg yolk
Adds richness and helps bind the batter together.
Sugar
Sweetens the batter and helps it brown as it bakes.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air bubbles that give lightness. Stirring vigorously deflates them, so the cupcakes come out dense instead of light and delicate.

Swap the lemon

How well each one fits the dish's main ingredients (egg, sugar, cream, flour):

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