Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Provides savoury flavour and body that holds the cake together with the potatoes.
- Potatoes
- Their starch binds the mixture and helps the surface turn crisp and golden when fried.
- Butter
- Fat that conducts heat evenly and adds richness and browning to the crust.
The step that matters
Invert the skillet onto the plate. The cake must be set and browned on the bottom before flipping. If it is undercooked, the potatoes are not yet bound by their starch and the cake will break apart when turned out.
Swap the potato
How well each one fits the dish's main ingredients (meat, pepper, butter):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits less well
- Mustardfits less well
Fit is the average pairing score against meat, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
