Why it works: Pepper and potato 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 ↓
Cod Cutlets
Ingredients
Directions
Prepare the fish
Steam the cod until nearly done.
Prepare a batter by mixing self-raising flour with 1 egg and enough water to achieve a smooth consistency.
Dip the piece of fish into the batter.
Place the battered fish in a pan.
Sprinkle pepper and coarse sea salt on the fish.
Fold the fish over when the batter sets.
Prepare the potatoes
Cut potatoes into small balls.
Fry the potato balls until golden.

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the cutlet, flaking into tender pieces when cooked.
- Self-raising flour
- Combines with egg and water to form a batter that coats the fish and sets when cooked.
- Egg
- Binds the batter and helps it set into a coating around the fish.
- Potatoes
- Starch in the potatoes browns in hot oil, giving the fried balls a golden crust.
The step that matters
Fold the fish over when the batter sets. Turning too early can tear the coating before it has firmed. Waiting until the batter sets lets it hold together, so the cutlet keeps its shape and cooks evenly.
Swap the potato
How well each one fits the dish's main ingredients (flour, egg, pepper):
- Spinachfits better
- Capsicumfits better
- Chivefits better
- Potatothe original
Fit is the average pairing score against flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
