Step 1
Sift the flour and salt into a large bowl. Add the egg and milk and beat with a wire whisk to make a smooth batter.

Step 2
Heat a small pancake pan or heavy-based frying pan, then add a tiny knob of Trex, swirling it around the pan until melted. Pour in a thin stream of batter, tilting the pan so that it flows evenly across the surface. Cook over a medium heat until set, then flip the pancake over to cook the other side. Cook 8 small pancakes altogether, adding a little Trex to the pan before cooking each one. Keep them in a warm place as you cook them, such as in a low oven.

Step 3
To make the sauce, put the sugar, syrup and butter into a saucepan and heat gently, stirring with a wooden spoon, until melted and smooth.

Step 4
Serve two pancakes per portion, topped with scoops of vanilla ice cream and hot butterscotch sauce.
