Wash the peppers and pat dry. Bake under a hot grill or in a preheated oven at 200 degrees for 10-15 minutes until the skin turns black and blisters. Peel off the skin, remove the stems and kernels from the pods and pass the pulp through a sieve or puree in a blender and add the garlic. Mix with paprika powder, salt, pepper, mustard powder and oil. Add vinegar and mix everything into a thick sauce.
Goes well with sliced avocados, vegetables or meat pies.
