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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Soak the butter in cold water if using salted butter, washing it several times to remove salt.
Beat the butter in a strong basin with a wooden spoon until it resembles Devonshire clotted cream.
Prepare a hoop by using a 6-inch wide slip of tin, fastening it with copper wire.
Make the batter
Gradually add sugar, flour, and eggs, mixing thoroughly after each addition.
Bake
Line the hoop with buttered paper and pour in the batter.
Bake in a preheated oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and gives a rich, tender crumb.
- Sugar
- Sweetens the cake and helps it brown while baking.
- Flour
- Forms the main structure that holds the cake together as it sets.
- Eggs
- Add structure, moisture and richness, and help bind the batter.
The step that matters
Adding the eggs gradually and mixing thoroughly after each addition. Adding eggs slowly lets each one emulsify fully into the butter. Adding them too fast can make the batter curdle, which leads to a coarse, heavy crumb.
“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.
