Why it works: Flour and sugar 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 moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg yolks well with the powdered sugar.
Add the salt and grated lemon rind.
Fold in the stiffly beaten egg whites.
Lightly mix in the flour.
Bake
Bake in muffin tins immediately in a moderate oven (350°F / 175°C).

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten whites trap air that lifts the puffs, and the yolks add richness and set structure.
- Flour
- Provides the starch and gluten network that gives the puffs their body once baked.
- Powdered sugar
- Sweetens the batter and dissolves easily into the beaten yolks for a smooth base.
- Lemon rind
- Adds bright citrus aroma from the oils in the grated peel.
The step that matters
Bake immediately after folding. Beaten egg whites hold their air only briefly. Delaying the bake lets the batter deflate, so the puffs rise less and turn dense.

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

- Figfits about as 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.
