Why it works: Flour and nuts 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 moderate 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).
Shape the macaroons
In a bowl, mix together the sugar, flour, egg, and chopped hickory nuts until well combined.
Flour your hands and shape the mixture into balls the size of hulled hickory nuts.
Place the balls on a greased baking pan, three inches apart.
Press half a hickory nut into the center of each ball.
Bake
Bake until light brown.

Flour and egg 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
- Binds the dough together and adds structure as it sets in the oven.
- Flour
- Provides structure so the balls hold their shape while baking.
- Sugar
- Sweetens the macaroons and helps them brown in the oven.
- Hickory nuts
- Supply the main flavor and fat, giving the macaroons their nutty taste and texture.
The step that matters
Shaping the balls. The dough should be firm enough to hold its shape. Flouring your hands keeps the sticky mixture from clinging, and evenly sized balls bake at the same rate so they brown uniformly.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, flour, egg):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Nutsthe original
Fit is the average pairing score against sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
