Preheat the oven to 425 degrees Fahrenheit. Line two baking sheets with parchment paper.
Make the batter:
Whisk together all of the ingredients until smooth. The batter should be fairly thick, but still thin enough to fall off of a spoon - this is to ensure excess batter can be gently shaken off of the cauliflower florets. Whisk in water a little bit at a time to thin if needed.
Make the bread crumb coating:
Stir together all of the ingredients for the coating.
Prepare the Thai peanut cauliflower wings:
One at a time, take the cauliflower florets and dip them in the batter, shaking off any excess. Transfer to the breadcrumb mixture and toss to coat, then place on the baking sheet, leaving room between the wings. This is easiest if you use two hands - one for picking up a floret, battering it, and dropping it into the bread crumb mixture; and the other hand for coating in the bread crumbs and placing on the baking sheet. See the step-by-step photos in the post for more assistance.
Once you have filled the baking sheet (taking care not to crowd it), bake the Thai peanut cauliflower wings for 16 to 22 minutes (may vary more depending on floret size and oven style), or until cauliflower is crisp-tender and batter is firm and lightly browned.
Prepare the sauce:
Whisk together all of the sauce ingredients. Adjust seasoning to taste. Drizzle over the cooked cauliflower wings or serve on the side as a dipping sauce (or both!). If serving to a crowd, I recommend using toothpicks and dipping. For a small group, we drizzle and then dip more to taste, but it gets a little messier.
Sprinkle roasted peanuts and green onions over the wings and sauce. Serve immediately.
Notes
Some brands of white rice flour can be gritty; I always use this superfine white rice flour made by Authentic Foods.GLUTEN-FREE: Simply use the white rice flour option and substitute gluten-free panko-style breadcrumbs. I've found those in recent times in the "International" aisle of my regular grocery store; there's a vegan variety made by Kikkoman. The ones in the pictures are actually gluten-free, as I wanted to share them with my love! Also, make sure to use tamari instead of soy sauce.THAI RED CURRY PASTE: This stuff luckily keeps for a long time in the fridge and I have many other recipes that use it (such as Thai butternut squash soup; triple P curry; and more)
