Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Mix all the ingredients together.
Beat the mixture thoroughly for 10 minutes.
Bake
Pour the batter into a cake tin.
Bake for 15 minutes in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato flour
- Forms the main body of the cake's crumb structure.
- Butter
- Adds richness and a tender, moist texture.
- Castor sugar
- Adds sweetness and helps give a tender crumb.
- Eggs
- Bind the batter and help set the cake's structure as it bakes.
The step that matters
Beat the mixture thoroughly for 10 minutes. Long beating incorporates air and fully combines the fat, sugar and eggs into a smooth emulsion. This airy batter gives the cake its rise and light texture, so under-beating can leave it dense.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter, cream, sugar, egg, lemon):
- Arrowrootfits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against flour, butter, cream, sugar, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
