Step 1 Place the cauliflower in a large bowl. Combine the turmeric, paprika, cumin and coriander in a small bowl.
Step 2 Use a small sieve to sift half of the spice mixture evenly over the cauliflower. Toss to combine. Sift over the remaining spice mixture and toss.
Step 3 Spray the cauliflower with oil and toss to coat. Place cauliflower in the basket of the air fryer and spray again with oil. Cook at 200°C for 15 minutes, turning cauliflower halfway through, until golden and crisp.
