Preheat the oven to 400 F.
Place the cauliflower in a metal pot and fill until 3/4 full of water. Add salt.
Cover with a lid, bring to a boil, lower to a moderate boil and cook for 10 to 15 minutes, depending on the size of the cauliflower.
Drain.
Brush the cauliflower with olive oil and sprinkle with a little salt and pepper, garlic powder and blackened seasoning.
Place in a baking dish in the centre of the oven, and bake until the top turns golden brown (about 60 minutes).
The outside of the cauliflower should be crisp and the inside as soft a butter.
Serve with the caesar-inspired yogurt sauce, sprinkle with cilantro and stake it with a knife for the fancy look
