Why it works: Nuts and flour are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,180 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Hickory Nut Macaroons
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make and bake
Mix the powdered sugar, chopped nuts, egg whites, flour, and baking powder together.
Drop spoonfuls of the mixture onto buttered paper or baking tins, spacing them apart.
Bake until light brown.

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
- Egg whites
- Whipped-free egg whites set the batter and give the macaroons their light, airy structure.
- Powdered sugar
- Adds sweetness and a fine, tender texture while helping the macaroons brown in the oven.
- Hickory nuts
- Provide the main flavor and richness, and their fat adds body and moisture.
- Baking powder
- Releases gas in the oven, helping the macaroons rise and lighten.
- Flour
- Adds a small amount of structure so the mixture holds its shape when dropped.
The step that matters
Bake until light brown. Sugar and egg whites darken quickly, and overbaking dries the macaroons and turns them bitter. Pulling them once they are light brown keeps them soft and moist inside.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, egg, flour):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Nutsthe original
Fit is the average pairing score against sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
