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 ↓

Ingredients
Directions
The book says “a gentle oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Crush and sift the bitter macaroons.
In a bowl, combine the macaroons and flour, creating a hollow in the center.
Add sugar, egg yolks, butter, and salt to the hollow.
Mix everything together until well combined.
Shape and bake
Form the mixture into small balls the size of olives.
Lightly brush the balls with egg wash.
Bake in a gentle oven at 350°F (175°C) until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bitter macaroons
- Provide the main almond-like flavor and tender crumb.
- Flour
- Builds the structure that holds the dough together.
- Egg yolks
- Add richness and bind the dough.
- Butter
- Adds fat for tenderness and a crisp, short texture.
- Sugar
- Sweetens the dough and helps the surface brown during baking.
The step that matters
Baking until light brown. Baking in a gentle oven dries the cookies evenly without over-browning them. Sugar darkens quickly at high heat, so checking for a light golden color prevents bitter, burnt edges.
