There really is no good substitution for Calabrian chiles, but you could chop roasted red bell peppers from a jar, which would be nice. I keep celery sticks crispy by placing them in a covered food storage container filled with ice water in the refrigerator until needed. You can let the roasted chicken wings cool and then hold in the refrigerator for up to 3 days in advance, or freeze them for up to a month in a vacuum-sealed bag. When you are ready to serve them, just pop them in a 350 degree F oven until they reach an internal temperature of 165 degrees F, 30 to 40 minutes, then proceed to the broiling step. Be sure to keep an eye on the wings when you are broiling them because they can get away from you pretty quickly. Buon Appetito! Blend the sauce in stages to prevent from overloading the blender or food processor. Doughgonzola dipping sauce is a killer dressing on a wedge salad!
