Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Sponge Drops

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

  1. Preheat the oven to 350°F (175°C).

  2. Beat the egg whites until stiff and dry, then gradually add the powdered sugar while continuing to beat.

  3. In a separate bowl, beat the egg yolks until thick and lemon colored.

  4. Gently fold the beaten yolks into the egg white mixture.

  5. Sift the flour with the salt and carefully fold it into the mixture.

Shape and bake

  1. Shape the batter into circles, three inches in diameter, on a baking sheet lined with unbuttered parchment paper.

  2. Sprinkle with powdered sugar and bake for eight minutes.

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

What each ingredient does

Egg whites
Whipped into a stiff foam that gives the drops their light, airy structure.
Egg yolks
Add richness and color, and their fat softens the texture of the whipped whites.
Flour
Provides just enough starch to set the batter into a sturdy, tender structure as it bakes.
Powdered sugar
Sweetens the batter and stabilizes the whipped whites while they are beaten.

The step that matters

Fold gently after adding the yolks and flour. Whipped egg white foam holds air that gives the drops their lift. Vigorous stirring deflates it, leaving dense, flat drops once baked.

Swap the vanilla

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

  1. Raisinfits better
  2. Vanillathe original
  3. Lemonfits less well
  4. Figfits less well

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