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 eggs steadily for four minutes.
In a bowl, mix warm water, warm milk, melted butter, and dissolved baking soda.
Carefully mix in the salted flour.
Fold in the beaten eggs until well combined.
Rise and bake
Pour the batter into a greased cake mold.
Let it rise until light, at least 6 hours or overnight in winter.
Bake in a preheated oven at 400°F (200°C) for 45 minutes if in one loaf, or 30 minutes if in two.

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
- Flour
- Gluten in the flour forms the network that gives the bread its structure.
- Yeast
- Yeast ferments sugars and releases gas, which makes the batter rise and turn light.
- Eggs
- Eggs add structure and richness, and help the batter hold its risen shape.
- Butter
- Melted butter adds fat, giving a tender crumb and rich flavor.
- Milk
- Milk adds moisture and softness, and helps the crust brown lightly.
The step that matters
Let it rise until light. Yeast needs enough time to produce gas and stretch the gluten network. Rising too briefly leaves a dense, heavy crumb, while the full rise builds the light, open texture.
