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 ↓
Potato Cake
Ingredients
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 the ingredients together until well combined.
Beat the mixture thoroughly for about 10 minutes.
Pour the batter into a greased cake tin.
Bake
Bake in a 400°F (200°C) oven for about 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato flour
- Provides the main starchy body, giving a light, tender crumb.
- Butter
- Adds fat for richness and a tender, moist texture.
- Castor sugar
- Sweetens the cake and helps it brown lightly in the oven.
- Eggs
- Add structure and help bind the batter as it sets.
The step that matters
Beat the mixture thoroughly. Beating traps air in the creamed butter and sugar, which expands in the oven and gives the cake lift. Under-beating leaves a dense, heavy cake.
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.
