Prepare and Bake the Cauliflower: Preheat your oven to 200°C (392°F). Line a baking tray with foil or parchment paper. In a small bowl, whisk together rice flour, cornstarch, oil, garlic powder, and water to create a smooth, thick batter. Coat the cauliflower florets thoroughly in this mixture, then arrange them in a single layer on your prepared baking tray. Bake for 20-25 minutes until the cauliflower is just tender but still retains its structure and crunch.
Create the Flavor-Packed Sauce: While the cauliflower bakes, combine sesame oil, soy sauce, rice wine vinegar, sriracha sauce, minced ginger, and garlic in a small saucepan. Simmer this aromatic mixture for 5-6 minutes, allowing the flavors to meld. If using maple syrup instead of honey, add it now. In a separate small bowl, whisk cornstarch with water until smooth, then stir this slurry into your simmering sauce. Continue cooking for another 2-3 minutes until the sauce thickens to a glossy consistency. Remove from heat and stir in honey for that perfect sweet-savory balance.
Combine and Serve: Once your cauliflower emerges from the oven with a golden, crispy coating, transfer it to a large mixing bowl. Pour the warm sauce over the florets and toss gently to coat each piece evenly. The sauce should cling beautifully to the crispy exterior. Transfer to a serving platter and garnish generously with sesame seeds, sliced spring onions, and fresh chillis for color, texture, and an extra flavor dimension.
Notes
Do not overcrowd your baking sheet – give each floret space to crisp up properly. This ensures maximum crunch and prevents steaming.
For extra flavor, consider adding a pinch of smoked paprika to your coating mixture. The subtle smokiness complements the sesame notes beautifully.
Timing is everything with the sauce. Make sure to add the cornstarch slurry only after the other ingredients have simmered together, creating a smooth, glossy finish.
Toss the cauliflower with the sauce immediately before serving to maintain that perfect crispy texture. The longer it sits, the more the coating will soften.
For a gluten-free version, use gluten-free soy sauce or tamari. The recipe is naturally gluten-free as written since rice flour and cornstarch are both gluten-free ingredients.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 180°C (350°F) oven for about 10 minutes to help restore some crispiness.
