Why it works: Lemon and rice are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,366 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter, sugar, and egg yolk together.
Add the rice flour and all-purpose flour, and work with your hands to form a paste.
Shape and bake
Roll out the dough thinly and cut into shapes.
Bake in a moderate oven at 350°F (175°C) until lightly golden.

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
- Adds fat and richness, and helps the biscuits turn tender and crumbly.
- Fine sugar
- Sweetens the biscuits and helps them brown lightly in the oven.
- Egg yolk
- Adds richness and helps bind the dough together.
- Rice flour
- Gives a fine, crisp, tender texture because it contains no gluten.
- All-purpose flour
- Provides some gluten structure so the dough holds its shape when cut.
The step that matters
Roll out the dough thinly. Thin dough bakes through evenly and turns crisp. Thick pieces stay soft in the middle and may brown unevenly before they dry out.
