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 ↓
Lemon Jumbles
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix the egg, sugar, butter, milk, lemon juice, lemon rind, cream of tartar, and baking soda until combined.
Add enough flour to form a soft dough, handling it as little as possible.
Shape and bake
Roll the dough very thin and cut it into round cakes.
Bake in the preheated oven until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the jumbles tender and rich.
- Sugar
- Adds sweetness and helps the cookies brown as they bake.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to help the cakes rise.
- Baking soda
- Reacts with the acid in the lemon and cream of tartar to produce lift and browning.
- Lemon juice
- Adds acidity and bright lemon flavor that balances the sweetness.
The step that matters
Handling the dough. Working the dough too much develops gluten, making the jumbles tough instead of tender. Mixing only until a soft dough forms keeps the texture light.
