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 ↓

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
Mix the milk and beaten eggs together.
Slowly add the flour, butter, sugar, and lemon rind, and mix well.
Bake
Bake in buttered saucers for 20 minutes at 400°F (200°C).

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
- Eggs
- Provide structure and help the batter set and puff as it bakes.
- Flour
- Gives the batter body so it holds its shape while baking.
- Butter
- Adds fat for richness and a tender texture.
- Milk
- Supplies the liquid that turns the batter into a pourable mixture and adds moisture.
- Sugar
- Adds sweetness and helps the puffs brown lightly in the oven.
The step that matters
Baking in buttered saucers. The butter greases the saucers so the puffs release cleanly. The batter is thin, so it must go into the hot oven promptly to rise and set before it deflates.
Swap the lemon

Fit is the average pairing score against milk, egg, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
