Season the flour with the rub. Dredge the crabs in the flour, coating evenly.

Heat the oil in a nonstick skillet over medium-high heat. Add the crabs, top side down. Cook for about 2 minutes, then turn them over and cook about 2 minutes more, or until golden. Remove from the heat. Transfer the crabs to a warm platter.

In another nonstick skillet, melt the butter over medium heat. Add the almonds and, shaking the pan back and forth, lightly toast them. Add the Worcestershire, lemon juice, parsley, and green onions. Stir for about 1 minute. Remove from the heat. Add the salt, black pepper, and cream. Stir to mix.

Spoon the sauce over the crabs and serve.
