Why it works: Peanut and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 1,754 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Peanut Paste
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Mix the brown sugar and pounded peanuts together.
Add the eggs and mix until well combined.
Grease a pan with butter and spread the mixture evenly in it.
Bake and serve
Bake in a moderate oven at 350°F (175°C) until light brown.
Once done, cut into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pounded peanuts
- Provide the main body and nutty flavor of the paste.
- Eggs
- Bind the mixture and help it set as it bakes.
- Brown sugar
- Adds sweetness and helps the surface brown during baking.
The step that matters
Bake until light brown. Baking until the surface is light brown sets the eggs and develops flavor. Pulling it too early leaves the paste soft and wet in the centre, while overbaking dries it out and makes it hard.
Swap the peanut
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Almondfits better
- Pecansfits better
- Filbertfits better
- Peanutthe original
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
