Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Bath Cakes and Jumbles
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Cream the butter and sugar together for 15 minutes.
Add 1 egg at a time, stirring for 5 minutes between each addition.
Gradually mix in the flour.
Shape and bake
Shape pieces of dough into worm-like forms, then twist them into circles on a well-floured board until they are the size of a five-shilling piece.
Place on a well-buttered baking sheet and bake at 400°F (200°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for tenderness and richness, and holds air when creamed with sugar.
- Sugar
- Sweetens the dough and helps trap air when creamed with butter, lightening the texture.
- Eggs
- Bind the dough and add moisture and richness to the cakes.
- Flour
- Provides starch and gluten that give the cakes their structure.
The step that matters
Creaming the butter and sugar. Beating butter and sugar together for the full 15 minutes works air into the fat, which gives the cakes a lighter, more tender crumb. If the mixture is under-creamed, the cakes will likely turn out denser.
