Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. 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 and mix
Weigh 10 eggs and use their weight in very fine sugar and 6 ounces of flour.
Beat the yolks with the flour and the whites separately until stiff.
Gradually mix the whites and flour with the yolks and beat well for 30 minutes.
Bake
Bake in a preheated oven at 400°F (200°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air that expands in the oven, giving the cake its light rise and airy structure.
- Very fine sugar
- Adds sweetness and helps stabilise the whipped egg foam so it holds its volume.
- Flour
- Provides the starch and gluten that set during baking to give the cake its firm crumb.
The step that matters
Gradually mixing the whites and flour into the yolks. Whipped whites are full of trapped air. Mixing too roughly or too quickly knocks that air out, so the cake bakes flat and dense. Fold gently and in stages to keep the foam intact.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, flour, brandy):

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