Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Almond Shortbread
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Ensure the ground almonds are fresh.
Mix the ground almonds, flour, and sugar together.
Carefully add a few drops of ratafia and mix thoroughly.
Make a space in the center and add the egg yolks.
Melt the butter, add it to the mixture, and combine until a firm paste forms.
Shape and bake
Roll the dough until it is a quarter of an inch thick and resembles cream-colored satin.
Cut into small squares with a sharp knife.
Pinch the edges of each square and place a split blanched almond in the center.
Butter baking tins and bake in a moderate oven at 350°F (175°C) until pale yellow.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground almonds
- Provide the main body and nutty flavor of the shortbread.
- Butter
- Adds richness and tenderness by coating flour particles and keeping the crumb short.
- Flour
- Gives the dough structure so it holds its shape when rolled and cut.
- Egg yolks
- Bind the dough and add richness and color to the crumb.
- Sugar
- Adds sweetness and helps the surface brown lightly during baking.
The step that matters
Roll to a quarter inch thickness. Dough rolled too thick bakes unevenly and stays doughy in the center, while dough rolled too thin can over-brown or dry out before the interior sets.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
