Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Adds fat and richness to the dressing, carrying the flavour of the other seasonings.
- Butter
- Adds fat and a rich flavour to the dressing base.
- Flour
- Thickens the butter and oil mixture so it can coat the salad smoothly.
- Mixed mustard
- Adds sharp, acidic flavour that cuts through the fat and the earthy vegetables.
- Codfish
- Provides the main fish flavour and protein of the salad.
The step that matters
Cooking the flour into the fat. Flour stirred into hot fat must be cooked briefly over low heat so it loses its raw taste and forms a smooth, thickened base. Heating too fast can scorch it or leave lumps, so the mixture should stay gentle and be stirred constantly.
Swap the carrot
