My favourite english dessert is the humble crumble, with whatever fruits that are in season. Also if you have fruits that are a bit pass their best but still edible, a crumple is a good way to not waste them.
I used this classic recipe (http://www.traditionalenglishpuddings.co.uk/a2applecrumble.html), but I substitute 100g of the flour with porridge oats to give a more crunchy topping. I also grated half an inch of ginger into the apple mix to make it a more adult dessert.
I made this for a dinner party, but for dinner for 2 or 3 people, you can make them in individuals ramekins, just use half the amount of ingredients and chopped the apples into smaller pieces.
