I made a dressing with a couple of spoons of oil, a little honey, some cumin, coriander, turmeric, salt and pepper. Peeled and cut up some carrots, tossed them in the dressing, added a couple of whole cloves of garlic and roasted them for about 40 minutes (until soft and slightly caramelised).
Once they'd cooled enough to handle, I put them in the processor (squeezing the garlic from its skin), added some tahini, lemon juice, and olive oil then blitzed until it looked right (and adjusting the quantities to taste).
