Why it works: Potato and beef are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,052 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Potato Cakes
Ingredients
Directions
Prepare
Mix the cold mashed potatoes with the beaten egg yolk until well combined.
Flour your hands and shape the mixture into cakes, similar to sausages.
Fry
Heat a skillet and grease it with hot beef drippings.
Place the cakes in the skillet, cover tightly, and cook for 5 minutes until the bottom is browned.
Turn the cakes, remove the cover, and fry until the other side is nicely browned.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mashed potatoes
- Form the main body of the cakes and hold their shape.
- Egg yolk
- Binds the potatoes together so the cakes hold their shape.
- Beef drippings
- Fat for frying that carries heat and browns the outside of the cakes.
The step that matters
Cover tightly during the first frying. Covering traps steam so the cakes cook through and the potato centres heat evenly. Removing the cover for the second side lets the surface dry and brown.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, beef):
- Chivefits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, flour, beef. Candidates are from the same food group and used in at least 100 recipes.
“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.
