Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Soft shell crab
Is the main protein; its thin shell is eaten whole when cooked.
Flour
Forms a light coating that helps the crab brown and crisp in the butter.
Butter
Conducts heat to the crab surface and adds browning and rich flavor.

The step that matters

Broil the crab in butter until cooked through. Soft shell crab cooks quickly, and overcooking dries the flesh and toughens it. Watching for a golden coating and opaque flesh helps prevent this.
