Preheat the oven to 200 °C.
Bring a saucepan of water with 1 teaspoon (5 ml) salt to a boil, then add the cauliflower head. Cook for 10 minutes, then drain and set aside.
Smoke the cauliflower by placing a hot charcoal disk inside a small foil container, then adding a handful of dried impepho herb. When the impepho starts smoking, place it inside a kettle braai with the cauliflower. Close the kettle braai lid and allow to smoke for at least 10-15 minutes. Remove from the kettle braai and set aside.
Quick hack: Use your oven as a smoker. Place the impepho on an oven tray, light it and when it starts to smoke place the tray on the bottom rack of the oven. Then place the cauliflower on the rack directly above the impepho. Close the oven and allow to smoke for 5-10 minutes.
Mix the garlic with the olive oil and brush over the whole cauliflower. Season with salt and pepper. Place on a baking tray and roast in the preheated oven for 30 minutes until crisp on the outside.
While the cauliflower is roasting, make the sauce by first roasting the peppers in the oven until the skins are blackened.
Remove the peppers from the oven and place in a bowl, cover with clingwrap and allow to cool for 10 minutes.
Once cooled, peel the skins off and blend the peppers, then set aside.
Heat the oil, then add the garlic and paprika, and cook for 2 minutes on medium heat. Add the blended peppers and cook for 5 minutes, stirring continuously to ensure that the sauce doesn’t stick and burn.
Add the lemon juice and brown sugar, cook for a further 2 minutes, then season with salt and pepper.
To serve, slice the cauliflower into steaks or leave whole, then place on a platter. Pour the sauce over the cauliflower and top with chopped herbs.
