Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soft shell crabs
- Form the main body of the dish and cook into a crisp, tender shell.
- Milk
- Helps the flour coating stick evenly to the crabs.
- Flour
- Forms a dry coating that fries to a crisp, golden-red crust.
- Lard or butter
- Conducts heat in deep frying and adds richness and browning to the crust.
The step that matters
Frying in deep, boiling fat. The fat must be hot enough to crisp the flour coating quickly. If it is too cool, the crabs absorb grease and turn soggy instead of crisp, and the coating may not brown evenly.
“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.
