Slice the Bratwurst only halfway (as per the video) through the sausage and use a cookie cutter to form the sausage into a circle.
Fry on both sides until hot and a nice colour is achieved (around 6 minutes).
While it’s cooking, slice the onion and add it to the pan alongside the sausage, you are looking to create essentially ‘burger onions’ like you’d get at a classic British burger stall, so just fried until golden amber and sweet.
Mix together the tomato ketchup, a little mild German mustard, a big pinch of curry powder, and a splash of hot sauce to create the curry sauce, and to get the right colour a little dash of gravy browning.
Once cooked place the now circular Bratwurst in a toasted white bun, top it with the onions, curry sauce and a big sprinkling of mild curry powder before the bun lid goes on.
