Do you like soda bread too mate? Not sure about sourdough, but I have a real easy recipe for cheese & jalapeño soda bread....
Not tried that either BB , but I would give it a go 👍
200g plain flour 150g wholemeal flour 50g oats 1tsp salt 1tsp baking powder 1tbsp lemon /lime juice or cider vinegar 300ml milk 1/2 cup of grated mature cheese Sliced jalapeños (chopped)
Mix all dry ingredients together. Add the lemon juice to the milk then add the milk to the mix. Make into a sticky dough. Turn into a floured loaf tin. Cook for around 30 mins at 200deg in a pre heated oven. Non dairy milk (soya,coconut etc) can be used instead of milk. For a lighter loaf, use all plain flour instead of wholemeal. Jalapeños to taste, I put at least a couple of tbsp in each loaf, & I also put in chopped sun dried tomatoes too. If no loaf tin available, just turn dough out onto a baking tray.
For a sweet version, use glace cherries, dates & chopped walnuts instead of the cheese & chilli's.
