Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt herring
- Forms the main body of the salad as the central flavour and protein.
- Mustard
- Adds sharp flavour and helps bind the oil and vinegar into a dressing.
- Oil
- Carries flavour and gives the dressing a smooth, rich texture.
- Tarragon vinegar
- Adds acidity that brightens the fish and balances the oil.
- Capers
- Contribute briny, sharp bursts of flavour that cut through the rich fish.
- Boiled potatoes
- Add soft starch and body, mellowing the sharpness of the dressing.
The step that matters
Mix the mustard, oil, and vinegar gradually. Adding the oil slowly while mixing lets the mustard emulsify it with the vinegar, so the dressing stays smooth instead of separating into greasy layers.
Swap the potato
How well each one fits the dish's main ingredients (mustard, beetroot, tarragon, vinegar, capers):
- Shallotfits better
