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 ↓

Souffle Biscuits

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. Rub the lemon rind into the sugar, then pound the sugar in a mortar.

  2. Beat the sugar into the yolks of the eggs.

  3. Add the heavy cream and flour, stirring lightly.

  4. Fold in the beaten egg whites.

Shape and bake

  1. Cut 3-inch square papers, turning up the edges half an inch.

  2. Fill the papers three-quarters full with the mixture.

  3. Bake in a 350°F (175°C) oven for 15 minutes.

Finish and serve

  1. Once done, shake sugar over the biscuits and serve immediately.

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

What each ingredient does

Eggs
Whipped whites and yolks create the airy lift that makes the biscuits light.
All-purpose flour
Provides the structure that holds the risen batter together as it bakes.
Sugar
Sweetens the biscuits and, when pounded with lemon rind, carries its aroma through the batter.
Heavy cream
Adds fat and moisture, giving the biscuits a tender crumb.

The step that matters

Folding in the beaten egg whites. Egg whites hold the air that makes a soufflé rise. Folding gently keeps that air in; stirring hard deflates the batter and yields dense biscuits.
