Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp or tench
- Firm white flesh forms the main body of the dish, cooked gently by boiling.
- Melted butter
- Adds richness and fat that complements the mild, lean flesh of the fish.
- Lemon
- Adds acidity that brightens the flavour of the mild boiled fish.
The step that matters
Boil the fish for 15 to 20 minutes if it's a moderate size. Boiling for too long toughens the proteins in the flesh and makes it dry and flaky. Timing depends on the fish's size, so a larger fish needs checking for doneness rather than following the same time.
Swap the lemon
How well each one fits the dish's main ingredients (parsley, butter, fish sauce):
- Limefits about as well
- Lemonthe original
- Coconutfits less well
- Mangofits less well
Fit is the average pairing score against parsley, butter, fish sauce. Candidates are from the same food group and used in at least 100 recipes.
