Method
- 1
Heat the oven to 220°C (200°C fan). Trim the leaves from the cauliflowers but leave the stalk on. Stand each one on its stalk and cut two thick steaks, about 2.5 cm wide, straight down through the middle. Keep the loose florets that fall off.
- 2
Mix the olive oil, cumin, paprika, turmeric and half the salt in a small bowl. Brush it over both sides of the steaks and toss any loose florets in what is left.
- 3
Lay everything on two large baking trays in a single layer. Roast for 25 to 30 minutes, turning the steaks over after 15, until deep golden at the edges and a knife slides into the thickest part.
25 min - 4
Meanwhile, whisk the tahini with the lemon zest, 3 tablespoons of lemon juice, the garlic, the rest of the salt and the cold water. It will look split at first, then turns smooth and pourable. Add a splash more water if it is too thick.

Put the steaks on warm plates and spoon over the sauce. Scatter with the parsley, sesame seeds and sumac. The sauce is also good with the loose florets, which crisp up even more than the steaks.
