Place the flour, baking powder and salt in a large bowl.
350 g self-raising flour, 2 tsp baking powder, 0.5 tsp salt
Add the Greek yoghurt, smoked paprika, tomato puree/paste and a couple of splashes of water (if needed) and stir until it forms a soft dough.
250 g Greek yoghurt, 2 tsp smoked paprika, 3 tbsp tomato puree
Place a folded piece of baking paper in the slow cooker pot. Fold another piece, place the dough on it and form into a round.
Cook on high, with a tea towel or a few pieces of kitchen paper under the lid to catch drips, for three hours.
For the last ten minutes, turn the loaf over to brown the top.
Use the baking paper to lift the loaf out. Cool slightly then slice and serve.
