Heat the oven to 350 degrees F (80 degrees C /Gas 4). Mix the icing sugar with the pecans on a baking tray and sprinkle with a little water to make a thick-ish paste.
Bake in the oven for a few minutes or until toasted and caramelized. Scoop out the ice cream into 4 glasses or bowls and sprinkle over the whole pecans then drizzle with a good glug of maple syrup.
