Preheat the oven to 220°C/200°C fan/gas 7. Line a baking tray with baking parchment.
In a bowl, combine the flour, milk, jerk paste, garlic powder and a good pinch each of salt and black pepper. Whisk until well combined into a thick batter.
Put the breadcrumbs, desiccated coconut and a small pinch of salt into a shallow dish and mix together.
Dip a cauliflower floret into the jerk batter and then toss in the breadcrumbs and coconut, until fully coated. Place on the lined baking tray. Repeat with the remaining florets.
Spray with a little oil and bake for 25–30 minutes until golden brown and crispy, turning the cauliflower pieces after 20 minutes.
Meanwhile, in a bowl mix together all the ingredients for the Jerk BBQ sauce. Adjust the jerk paste according to taste.
When the cauliflower bites are cooked, place on a serving platter and scatter over the spring onions. Serve immediately with the BBQ sauce for dipping.
