Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chocolate Macaroons
Ingredients
Directions
Prepare
Finely scrape down 1 lb of prepared cocoa.
Beat the egg whites until stiff peaks form.
Lightly grease the bottom of oblong tin pans with sweet oil or butter.
Make and bake
Gradually mix in 1 lb of powdered sugar and the cocoa, adding a little sifted flour if the mixture is too thin.
Form the mixture into small, thick cakes and place them in the pan, leaving space between each.
Bake for a few minutes until set, then sift sugar over them while warm.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Egg whites
- Whipped into stiff peaks to give the macaroons lightness and a structure that holds the batter together.
- Powdered sugar
- Adds sweetness and dissolves into the whipped whites, helping the cakes set with a fine crumb.
- Prepared cocoa
- Provides the chocolate flavour and dark colour and adds bulk to the batter.
- Sifted flour
- Stiffens the mixture if it is too thin, adding structure to the cakes.
The step that matters
Gradually mixing in the sugar and cocoa. Folding dry ingredients into whipped egg whites too quickly or too vigorously deflates the foam, so the cakes spread thin and lose their lift. Adding them slowly keeps the air bubbles intact.
Swap the cocoa
How well each one fits the dish's main ingredients (egg, sugar, flour, butter):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits better
- Cocoathe original
Fit is the average pairing score against egg, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
