Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries flavor and moisture, and helps the crab brown as it cooks.
- Salted flour
- Forms a light coating that helps the crab hold its moisture and brown in the broiler.
- Lemon juice
- Adds acidity that brightens the rich butter.
The step that matters
Dredge the crabs well in salted flour. A thin, even flour coating helps the crab brown and seals in moisture during broiling. Patchy or thick coating can burn in some spots or leave others pale and dry.
“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.
