Preheat oven to 450 degrees F/230 degrees C. Line a baking sheet with a silicone baking sheet or greased foil. Using a knife, remove florets from the cauliflower (aka cut off the leaves and don't use the stems).
In a bowl, mix the flour, chilli paste, cornstarch, nut milk, ACV, sea salt, ground black pepper, garlic powder and onion powder. Stir to combine - the batter should be like a sticky tempura batter. If the batter is too thick, feel free to thin it out with some more milk and vice versa.
In a separate bowl, place the panko breadcrumbs. Line it up beside the batter bowl. Toss the cauliflower in the batter mixture (you can add them all at once), using a spatula or spoon to coat them all.
Then, transfer them to the panko breadcrumbs (you can do this in two or three batches) to coat completely, then place onto the baking sheet, giving each floret enough space.
Bake for 22 minutes. Please ensure your oven is completely preheated and hot.
Remove from oven. Toss the battered baked cauliflower in the sauce (I like to use a spatula to move them around to get properly coated) then using tongs or a spoon, remove and place back on the baking sheet. Bake for another 1-2 minutes for the sauce to soak into the wings.
Remove from oven, top with sesame seeds, eat immediately and enjoy!
