Why it works: Cabbage and pepper are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 4,081 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare
Mash the cold cabbage and potatoes well with a ladle.
Add pepper and coarse sea salt to the mixture.
Fry and brown
Heat hot dripping or bacon fat in a frying pan.
Turn the mixture into the frying pan, stir well, and cover.
Once heated through, remove the cover, shape into a flat cake, and brown on both sides.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cabbage
- Provides the bulk and the sweet, slightly earthy flavour of the dish.
- Cold potatoes
- Binds the mixture together and gives a soft, starchy body that holds the cake shape.
- Hot dripping or bacon fat
- Conducts heat to the mixture and adds richness, helping the outside brown.
The step that matters
Browning the cake on both sides. The cake must be heated through under cover first, then left uncovered so moisture escapes and the surface can brown. Covering it throughout would steam the outside instead of crisping it.

Fit is the average pairing score against cabbage, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
