Why it works: Cabbage and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 3,001 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
- Lettuce or endive
- Forms the bulk of the dish and softens into a tender, moist texture when stewed.
- Green onions
- Browning in butter builds a sweet, savoury aroma that flavours the greens.
- Clarified butter
- Provides fat for frying the onions and carries flavour without burning as easily as whole butter.
- Peas
- Add sweetness and a tender bite that contrasts with the soft greens.
The step that matters
Stew gently until cooked, then drain on a sieve. Gentle heat softens the leaves evenly without toughening or breaking them down. Draining removes released water so the dish does not turn soggy or watery.
Swap the peas
