01 - Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or a silicone baking mat.
02 - In a large mixing bowl, combine the all-purpose flour, cornstarch, garlic powder, salt, and black pepper. Gradually incorporate the cold water while whisking vigorously to achieve a smooth, thick batter consistency.
03 - Submerge each cauliflower floret into the prepared batter, ensuring it's fully coated. Allow any excess batter to drip off before transferring the coated floret to the panko breadcrumbs. Gently press to adhere the breadcrumbs. Arrange the breaded florets in a single layer on the prepared baking sheet.
04 - Bake for 22 to 25 minutes, flipping the florets halfway through the cooking time, until they are golden brown and achieve a crispy texture.
05 - While the cauliflower bakes, combine the honey, Sriracha sauce, soy sauce, rice vinegar, butter, and sesame oil in a small saucepan. Place over medium heat and simmer, stirring constantly, until the butter melts and the sauce becomes glossy, approximately 2 to 3 minutes. Remove from heat.
06 - Once the cauliflower is baked, let it cool for 2 minutes. Transfer the crispy florets to a large bowl and pour the prepared glaze over them. Gently toss to ensure all the cauliflower bites are evenly coated. Toss gently to coat.
07 - Serve immediately. Garnish with fresh cilantro, toasted sesame seeds, and lime wedges, if desired.
