Stir the cheeses, cornflour, cream and 1 tbsp maple syrup in a saucepan over a low heat. Continue stirring – it may split or look lumpy but will eventually come together. Season with the Tabasco and a little more maple syrup to taste. Keep warm to prevent it setting quickly.
Grill the bacon until very crisp, and warm the tortilla chips on the shelf below in the oven. Heap the chips onto a platter and pour over the cheese sauce. Break the bacon into small pieces and sprinkle over, followed by the spring onions, jalapeño (if using) and coriander.
