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.
- Egg
- Helps bind the mixture and sets it as it cooks.
- Breadcrumbs
- Form a crisp, golden outer coating when fried.
The step that matters
Cook the mixture for 5 minutes. The egg in the mixture sets when heated, which helps the croquettes hold their shape. Cooking the mixture until it is firm and then chilling it before shaping makes it easier to form and less likely to fall apart.
