Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrot
- Adds sweetness and colour, and holds its shape in the julienne cut.
- Turnip
- Adds a mildly sharp, earthy flavour to the stock.
- Onions
- Browning in the fat builds sweet, savoury depth for the broth.
- Stock
- Forms the liquid base that carries the flavour of the vegetables.
The step that matters
Frying the slices until brown. Browning the vegetables in butter creates deeper, roasted flavours through the Maillard reaction and caramelisation. Pale slices give a flatter, blander soup, so colour them evenly without burning.
Swap the peas
The recipe marks peas as optional. How well each one fits the dish's main ingredients (carrot, turnip, celery, onion, pepper):
- Lentilsfits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against carrot, turnip, celery, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
