Mix 1/2 pound of crab, 6 scallions (cut up), 6 ounces of mozzarella cheese, 6 ounces of cheddar cheese, and just enough mayonnaise to make it stick. Add a dash of salt and cayenne pepper.
Remove buttermilk flake biscuits from refrigerated tube. Tear flakes apart. Slather the mixture on top of each, then cook per the biscuit directions.
Best when still warm. Number of servings depends on the size of biscuits and the thickness of the topping.
