Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Nut Wafers
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.
Make the batter
Cream the butter in a bowl using a wooden spoon.
Gradually add the sugar while stirring and beating constantly.
Mix in the beaten eggs until well combined.
Sift together the baking powder, salt, and pastry flour, then add to the mixture.
Stir in the milk, chopped peanuts, and lemon juice until just combined.
Shape and bake
Drop teaspoonfuls of the batter onto an ungreased baking sheet, spacing them one inch apart.
Place half a peanut on top of each cookie.
Bake in a 300°F (150°C) oven for 15 minutes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Creams with sugar to trap air and give the wafers a tender, rich texture.
- Eggs
- Bind the batter and add structure and moisture as they set in the oven.
- Baking powder
- Releases gas in the batter, helping the wafers rise and turn light.
- Pastry flour
- Provides low-protein structure, keeping the wafers tender rather than tough.
- Finely chopped peanuts
- Add nutty flavor and a bit of texture throughout the wafers.
The step that matters
Stirring in the milk, peanuts, and lemon juice. Mixing only until just combined keeps the batter tender. Overworking the flour develops gluten, which makes the wafers tough and dense.
Swap the peanut
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, lemon):
- Almondfits better
- Pistachiofits better
- Milletfits better
- Peanutthe original
Fit is the average pairing score against butter, sugar, egg, flour, milk, lemon. Candidates are from the same food group and used in at least 100 recipes.
