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 ↓
Hazel-nut Cakes
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Mince the hazel-nuts and sweet almonds very finely.
Make the paste
In a bowl, combine the minced nuts, powdered sugar, and beaten egg white.
Add enough flour to bind the mixture together.
Roll out the paste to ¼ inch thick and stamp out small round cakes.
Bake
Place the cakes on well-buttered baking tins.
Bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hazel-nuts
- Provide the main flavor and fat, giving the cakes a rich, nutty body.
- Sweet almonds
- Add nutty aroma and body alongside the hazelnuts in the paste.
- Powdered sugar
- Sweetens the paste and helps it bake to a fine, tender texture.
- Egg white
- Adds structure and lightness, binding the nuts and sugar into a workable paste.
- Flour
- Binds the mixture so it can be rolled out and stamped into cakes.
The step that matters
Mincing the nuts very finely. Coarse pieces of nut stop the paste from binding smoothly and cause uneven texture and spreading. Fine mincing lets the egg white and sugar coat the nut particles evenly, giving a cohesive dough that holds its shape.
Swap the nuts
How well each one fits the dish's main ingredients (almond, sugar, egg, flour):
- Pistachiofits better
- Cashew nutfits better
- Macadamia nutfits better
- Nutsthe original
Fit is the average pairing score against almond, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
