Try these NYC-inspired hot dogs: frankfurters topped with classic caramelised onions, ketchup, American mustard and a little sauerkraut. A great after-school meal between after-school clubs.
Based on 4 servings, adjust as needed.
First, make the onions. Heat the oil in a frying pan over a low-medium heat and cook the onions for 10-12 mins until golden and slightly charred in spots.
Stir in the cinnamon, chilli powder, honey, mustard, ketchup, tomato purée, vinegar, Worcestershire sauce, 2-3 tbsp water (if cooking for 4) and a pinch of salt. Simmer for 1-2 mins until the onions are saucy, adding a splash more water if they seem dry. Taste and add a little more chilli powder, mustard or a pinch of sugar, if you like. Keep the onions warm if you’re serving straightaway or cool and chill. Will keep in an airtight container in the fridge for up to five days. Reheat over a low heat before serving, adding a splash of water to loosen as needed.
Cook the frankfurters for 15 mins in a griddle pan until charred (of bbq if it's the season!), or for 8 mins in a pan of simmering water. If using a barbecue, warm the buns over the coals, if you like. Spoon a little sauerkraut into each bun, top with a frankfurter and spoon over the onions. Drizzle over some extra mustard and ketchup.
