Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Peanut Macaroons
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.
Make the meringue
Add a pinch of salt to the egg whites and beat until light.
Mix cream of tartar and sugar together, then add to the egg whites, beating until very stiff.
Fold and bake
Combine flour, cinnamon, and peanuts, then fold into the egg mixture.
Drop spoonfuls onto a greased baking sheet and bake at 350°F (175°C) until done.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 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 foam, they create the light structure that holds the macaroons together.
- Granulated sugar
- Stabilizes the whipped whites and adds sweetness and browning as the macaroons bake.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stable, stiff foam.
- Finely chopped peanuts
- Add body, texture and nutty flavor to the batter.
- Flour
- Adds a small amount of structure so the macaroons hold their shape.
The step that matters
Beating the egg whites until very stiff. Under-whipped whites collapse when the dry ingredients are folded in, and the macaroons spread and bake flat. Stiff, stable foam traps air that gives lift and a light crumb.
Swap the peanut
How well each one fits the dish's main ingredients (egg, flour, cinnamon, cream, sugar):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Peanutthe original
Fit is the average pairing score against egg, flour, cinnamon, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
