Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Soften the yeast in a little warm milk.
Add the yeast mixture to the remaining milk with the salt.
Stir in enough flour to make a muffin batter.
Let the batter stand overnight.
Rise and bake
In the morning, add the melted butter and the baking soda dissolved in 1 tablespoon of hot water.
Beat the mixture thoroughly.
Place in well-oiled muffin tins, filling them half full.
Let rise for about 25 minutes.
Bake in a hot oven at 400°F (200°C) until golden.

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
- Bread flour
- Forms the gluten network that gives the batter its structure and holds the bubbles.
- Compressed yeast
- Produces carbon dioxide gas during fermentation, which makes the crumpets rise and become airy.
- Milk
- Provides the liquid that hydrates the flour and dissolves the yeast into a workable batter.
- Baking soda
- Reacts with the batter's acidity to release extra gas, adding lift and open holes.
- Melted butter
- Adds fat that softens the crumb and gives a richer flavor and texture.
The step that matters
Beat the mixture thoroughly. Beating develops the gluten and evenly distributes the gas-producing yeast and baking soda, so the batter rises evenly and forms a uniform, open crumb rather than dense patches.
“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.
