Pat cauliflower florets dry with a paper towel or let them air dry in a colander.
Whisk together batter ingredients in a bowl until well combined. The batter should be thick enough to coat the florets
Preheat oven to 450°F [230°C]. Dredge cauliflower florets in the batter, shake off excess & place them on a lined baking sheet.
Brush or spray each floret with oil & bake until golden brown for about 20 mins, flipping halfway. (You can also turn the broiler to low & broil for about 3 mins to get the roasted look at the top)
Place the sauce ingredients in a saucepan, turn on the heat & bring it to a low simmer. Stir & cook until sauce is slightly thickened.
Quickly toss florets with the sauce & serve immediately with a sprinkle of chopped cilantro or scallions.
