A whole cauliflower is marinated in a sweet-and-spicy sauce, pressure cooked in an Instant Pot, then glazed and broiled until caramelized.
If using a small cauliflower head, 1 minute on high pressure might be enough (we tested this recipe many times starting with a small not-so-dense cauliflower, and 1 minute worked fine). If using a large and dense cauliflower head, set at 8 minutes. For a medium cauliflower head, set at 4 minutes.
Place on a sheet pan and brown it under the broiler for 7-10 minutes for a lovely crust. Make sure that your oven is preheated, and keep an eye on it as it’s being broiled and decide how long do you need to broil it for.
I highly recommend glazing the cauliflower head twice for maximum flavor (after pressure cooking). Glaze then broil for a few minutes, then take it out glaze again, and broil for a few more minutes.
The original recipe was slightly tweaked, we added ketchup to the marinade for flavor and color.
