Why it works: Butter and flour 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 ↓
Nut Cookies
Ingredients
Directions
The book says “a very 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).
Make the dough
Cream the butter, then add the sugar and beaten eggs.
Sift together the flour and baking powder, then mix into the butter mixture.
Stir in the chopped nuts and lemon juice.
Bake
Drop spoonfuls onto an ungreased baking sheet, leaving an inch between each.
Sprinkle with additional chopped nuts and bake.

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
- Creamed with sugar to give the cookies richness and a tender texture.
- Eggs
- Bind the dough and add structure as they set in the oven.
- All-purpose flour
- Forms the main structure that holds the cookies together as they bake.
- Baking powder
- Releases gas in the dough so the cookies rise and turn lighter.
- Chopped nuts
- Add crunch and a toasty flavour to the cookies.
The step that matters
Leaving space between spoonfuls. Dropped dough spreads as it bakes, so cookies placed too close can merge and bake unevenly. Leaving an inch between each gives every cookie room to spread and brown evenly.
Swap the nuts
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, lemon):
- Almondfits better
- Pistachiofits better
- Milletfits better
- Nutsthe original
Fit is the average pairing score against butter, sugar, egg, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
