Spread the cauliflower florets on a baking sheet, and char under the broiler for 10 minutes at 200c (395f). This will help the cauliflower get going.
In a heavy bottom pan, melt the coconut oil. Add the minced garlic and grated ginger, and cook until fragrant (about 1 minute). Add all of the spices, sugar, and salt, stir and cook for a minute then add the passata, followed by the coconut milk.
Add the cauliflower to the sauce, and simmer until the cauliflower is cooked and sauce reduce a little. This should take around 10 minutes.
Serve warm over basmati rice with chopped parsley, mint, or cilantro.
