The prep time actually varies a bit, depending on whether you bought your cauliflower pre-cut. If you have to cut up the cauliflower before you start cooking, allow another 5 minutes or so.
Buffalo cauliflower doesn't stay crunchy for long, so eat these immediately for maximum goodness. I'd recommend reheating these in the air fryer, so they'll get crunchy again. I gave some of these to my neighbor during testing, and he reheated them in the oven with good results, also. If you reheat in the microwave, they'll definitely be mushy.
