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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the codfish
Soak codfish overnight in fresh water.
Boil codfish for 1 hour and 15 minutes, then drain and remove bones.
Chop the codfish.
Make the cakes
Boil potatoes until tender.
Mash potatoes and mix with codfish, butter, eggs, and pepper.
Form mixture into cakes.
Bake
Place cakes in pans and bake in a 400°F (200°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flaky protein and bulk of the cakes.
- Potatoes
- Starch binds the mixture and gives the cakes a soft, tender body.
- Butter
- Adds fat for richness and moisture in the mashed mixture.
- Eggs
- Bind the mixture so the cakes hold their shape while baking.
- Pepper
- Adds aroma and gentle heat to the fish and potato mixture.
The step that matters
Mash potatoes and mix with codfish, butter, eggs, and pepper.. Potatoes that are still lumpy or overworked change the texture. Mixing gently until evenly combined keeps the cakes moist and cohesive enough to form and brown without falling apart.
Swap the potato
