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.
