Preheat oven to 425°.
Chop the cauliflower into florets and place on a large baking sheet.
In a small bowl, whisk together coconut oil, curry powder, salt and cayenne.
Pour oil mixture over the cauliflower and toss to coat evenly.
Roast for 20 minutes, then flip and roast for an additional 20 minutes.
Remove from the oven and top with raisins, celery and parsley. Toss to combine and serve immediately.
