Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soft-shelled crabs
- The main ingredient, eaten whole once its shell is softened and lightly browned.
- Melted butter
- Adds fat and richness, carries the seasoning, and helps the shells brown under heat.
The step that matters
Broil until the shells are only slightly brown. Direct heat browns the shell through Maillard reactions and caramelization. Leaving the crabs under the broiler too long dries the delicate meat, so watch them closely.
