Why it works: Walnut and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,149 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

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
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and sugar together.
Add the eggs, walnut meats, baking powder, and lemon extract; mix well.
Gradually add flour until the dough is manageable but still soft.
Shape and bake
Roll the dough thin and cut into desired shapes.
Place on a baking sheet, sift sugar on top, and bake until very light brown.

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 give the cookies richness and a tender texture.
- Sugar
- Sweetens the dough and, sifted on top, helps the surface brown.
- Eggs
- Bind the dough and add structure and moisture as it bakes.
- Walnut meats
- Add nutty flavor and a bit of texture to the cookies.
- Baking powder
- Releases gas in the dough to lighten the cookies as they bake.
- Flour
- Provides the structure that holds the cookies together once baked.
The step that matters
Bake until very light brown. Sugar browns quickly at 350°F, so the cookies can go from pale to over-browned in a short time. Pulling them at a very light brown keeps them tender and prevents bitterness from scorching.
