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
Make the batter
Mix flour, egg, melted butter, milk, and yeast together until well combined.
Let the mixture rise for 2 to 3 hours.
Cook
Pour the batter onto a hot, greased frying pan like pancakes.
Cook until the bottom is golden, then carefully turn to cook the other side.

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
- Yeast
- Produces gas during the rise, giving crumpets their airy texture and holes.
- Flour
- Provides the structure that holds the risen batter together as it cooks.
- Egg
- Adds richness and helps bind the batter.
- Milk
- Supplies the liquid that hydrates the flour and makes the batter pourable.
- Butter
- Adds fat for richness and softness in the finished crumpets.
The step that matters
Let the mixture rise for 2 to 3 hours. Yeast needs time to ferment and release gas; rising too briefly leaves the batter dense and the crumpets without their characteristic holes.
“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.
