Flaky, all-butter golden pastry filled with a delicately spiced sweet filling, baked until crisp and aromatic.
Warm the milk to 32C, stir in the rennet, cover, and leave for 1 hour until firmly set.
Cut the curd into cubes and drain it in a cloth for 30 minutes, reserving the whey.
Heat the reserved whey to 80C, add the curd in pieces, and let it soften until molten.
With oiled hands, stretch and fold the cheese repeatedly, working in the nigella seeds and fine salt.
Roll the cheese into long ropes, braid them together, and press the ends to seal.
Rest the braid in the cold water with the coarse salt for 1 hour, then slice and serve with tomato and mint.
