Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roe
- Forms the main body of the salad, giving it a firm, flaky texture once poached.
- Mayonnaise or mustard dressing
- Adds moisture and richness, coating the diced roe and binding the salad together.
- Onion
- Its cut side is rubbed on the plate, lending a faint aromatic flavour to the dressing.
The step that matters
Boil gently for 20 minutes. Boiling vigorously can toughen and break up the delicate roe, so a gentle simmer keeps it tender and intact for dicing.
Swap the onion
How well each one fits the dish's main ingredients (roe, mustard, lettuce):
- Horseradishfits better
- Chivefits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against roe, mustard, lettuce. Candidates are from the same food group and used in at least 100 recipes.
