In a shallow bowl or plate combine the flour, 1 1/2 teaspoons of the salt, pepper, cayenne, and garlic powder and stir to combine thoroughly. Quickly dredge the veal scallops in the seasoned flour mixture, shaking to remove any excess flour

Heat the oil in a large skillet over medium-high heat until very hot but not smoking. Add 1 1/2 tablespoons of the butter and, working quickly and in batches if necessary, cook the veal until golden brown on both sides, about 1 minute per side. Transfer to a plate and set aside.

Add 1 tablespoon butter to pan and cook garlic, shallots, and capers for about a minute. Deglaze the pan with wine and bring to a boil, scraping to remove any browned bits from the bottom of the pan. When the wine has reduced by half, add the chicken stock and lemon juice and cook for 5 minutes, or until the sauce has thickened slightly.

Whisk in the remaining 1/2 teaspoon of salt, remaining 3 1/2 tablespoons of butter and the chopped parsley. When the butter has melted, return the veal scallops to the pan and cook until heated through and the sauce has thickened, about 1 minute. Garnish with parsley sprigs and serve immediately.
