Heat oil to 350° in large wok or pot. I used a cast iron skillet but you could use a deep fryer too! Or, if you’d like a bit healthier option and skip the frying, try using an air fryer.
Add cauliflower to batter and coat. Add cauliflower pieces, one at a time, to hot oil (allow excess batter to drip off). Don’t overcrowd pan. Will need to cook in a couple batches. Rotate and agitate pieces until crisp and golden brown. Remove and drain on paper towels, sprinkle. with. salt. Continue cooking until. all. cauliflower is cooked.
In large bowl, toss cauliflower pieces with chili sauce. Garnish with sesame seeds and sliced scallions.
