Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salsify
- The main vegetable, whose tender flesh becomes the dish once boiled.
- Butter
- Adds richness and a smooth, fatty mouthfeel to the cooked salsify.
- Lemon juice
- Adds acidity that brightens the mild, earthy flavour of the salsify.
- Vinegar
- Its acidity helps salsify keep its pale colour while boiling.
The step that matters
Adding vinegar to the boiling water. Salsify discolours when its flesh is exposed to air and heat. A little acid in the cooking water helps it stay pale, so the vinegar should be added while it boils.
Swap the lemon
How well each one fits the dish's main ingredients (vinegar, butter, pepper):
- Lemonthe original
- Mangofits about as well
- Plumfits about as well
- Cherryfits less well
Fit is the average pairing score against vinegar, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
