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.
Make the batter
Beat the sugar and eggs together until well combined.
Mix the cream of tartar with the milk and add it to the sugar and egg mixture.
Stir in enough flour to create a thin batter.
Add the baking soda and salt, and stir briskly.
Bake and serve
Pour the batter into a buttered pan.
Bake in a preheated oven at 400°F (200°C) until golden.
Serve with vinegar sauce.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter 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 richness, helping the batter set and hold its shape when baked.
- Baking soda
- Reacts with the cream of tartar to release gas, helping the bun rise.
- Cream of tartar
- Acidic partner to the baking soda, producing gas bubbles and stabilizing the batter.
- Sugar
- Adds sweetness and helps the crumb brown during baking.
- Flour
- Forms the gluten and starch network that gives the bun its body once baked.
The step that matters
Add the baking soda and salt, and stir briskly. Baking soda reacts with the acid in the cream of tartar right away, so the batter should go into the pan and oven promptly. Waiting lets the gas escape before baking sets the crumb, which can leave the bun flat.
