Why it works: Milk and butter 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the stiff dough together as it bakes.
- Butter
- Adds fat for a tender texture and rich flavour.
- Eggs
- Bind the dough and add structure and richness.
- Sugar
- Adds sweetness and helps the cookies brown.
- Lemon
- Its juice adds acidity and its peel adds bright aroma.
- Baking soda
- Reacts with the lemon acid to give lift and a lighter crumb.
The step that matters
Adding the soda and milk last. Soda needs acid from the lemon to react and produce lift, so it should be mixed in once and evenly. Beating the dough too long after that can toughen the cookies.
Swap the lemon
