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 ↓

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.
Make the batter
Cream the butter and sugar together.
Add the beaten eggs and milk, mixing well.
Sift together the baking soda, cream of tartar, and flour.
Gradually add the dry ingredients to the wet mixture.
Fold in the dried orange peel and nut meats.
Bake
Drop spoonfuls of the batter far apart on a baking sheet.
Bake in a quick oven at 400°F (200°C) until golden.

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, giving the cakes a tender crumb.
- Eggs
- Provide structure and binding as the batter sets in the oven.
- Baking soda
- Reacts with the cream of tartar to produce gas that lifts the batter.
- Cream of tartar
- Acidifies the batter so the baking soda reacts and helps the cakes rise.
- Flour
- Forms the main structure that holds the cakes together as they bake.
- Dried orange peel
- Contributes concentrated citrus aroma and a slightly bitter flavour.
The step that matters
Spacing the batter on the baking sheet. Drops of batter spread as they bake, so placing them far apart keeps the cakes from merging. Baking soda and cream of tartar must be combined into the batter promptly, because their leavening gas is released during mixing and baking.

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