Mix together all ingredients for batter, except breadcrumbs, in a bowl. Batter should be slightly thinner than pancake batter. Add cauliflower florets to bowl and toss to coat.
One by one, remove cauliflower from batter with a fork, letting excess drip off, and transfer to oiled parchment lined baking sheets, being sure not to overcrowd. Sprinkle generously with breadcrumbs if using. Spray with a very light coat of olive oil. (optional for extra crispiness!)
Bake for 25 minutes until golden and crisp.
Purée all ingredients for sauce in a blender until smooth. Pour into a small saucepan over low heat. Adjust spice, sweetness, and saltiness to your liking. Simmer for 5-10 min.
Remove cauliflower from oven and let cool for 3-5 min (this step is very important as it prevents the cauliflower from getting soggy!)
Transfer cauliflower to a bowl and toss gently with sauce. Sprinkle with green onion.
Serve hot with steamed rice and broccolini!
