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 sponge
In a bowl, combine sweet milk, melted butter, and eggs.
Stir in baking soda and yeast.
Add flour gradually until a stiff sponge forms.
Transfer the mixture to buttered pans and let it rise until supper.
Bake and serve
Preheat the oven to 400°F (200°C).
Bake for 20 minutes.
Once baked, use a sharp knife to divide the top from the bottom.
Butter the inside and reassemble, then serve hot.

The flavor team
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.

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
- Add structure and richness to the sponge as it sets in the oven.
- Yeast
- Produces gas as it ferments, lifting the sponge so it rises and becomes airy.
- Flour
- Forms the gluten network that gives the bread its structure and holds the rise.
- Baking soda
- Reacts with acid in the batter to release gas, adding extra lift.
- Sweet milk
- Adds moisture and tenderness, and helps the dough hydrate with the flour.
- Butter
- Adds fat that softens the crumb and gives a richer flavour.
The step that matters
Letting the sponge rise. The sponge needs enough time to rise fully before baking. Yeast gas builds the open crumb, and an underproofed sponge will bake dense and heavy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
