Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

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 croquettes and gives them their rich flavour.
- Heavy white sauce
- Binds the chopped roe together and keeps the mixture moist inside.
- Egg
- Helps bind the sauce and, as a coating, gives the breadcrumbs something to stick to.
- Breadcrumbs
- Form a crisp, golden outer crust when the croquettes are fried.
The step that matters
Let the mixture cool fully before shaping. A warm, soft mixture will not hold its shape and may break or slump when coated. Cooling lets the white sauce set so the croquettes keep their form.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
