Step 1: Simmer the 4 pork frankfurters in water for 5 minutes, until hot right through (at least 160°F in the centre). Drain and slice each in half lengthways.

Step 2: Split the 4 slim crusty bread rolls lengthways without cutting all the way through. Line each with 2 slices of 8 slices sliced mild cheese and the sausage halves.

Step 3: Brush the outsides of the rolls with the 1 oz butter. Toast in a sandwich press, or in a heavy frying pan over a medium heat pressed down with another pan, for 3–4 minutes per side, until very crisp and the cheese has melted.

Step 4: Meanwhile, warm the 4 tbsp tomato ketchup, 1 tbsp mild mustard, 2 tsp hot chilli sauce (piri-piri), ½ tsp sweet paprika and 3 tbsp water in a small pan, stirring, for 2 minutes until smooth and glossy.

Step 5: Cut each roll into 2 cm slices, arrange on a plate and spoon the hot sauce over. A common mistake is pouring the sauce on too early: eat at once while the bread is still crunchy.
