Crumble time

For more than two months now, I have been cooking apple crumble most evenings. Many reasons for that: an easy way to have my kids eating fruits (albeit cooked hence loosing some of the benefits!), apples are really cheap at this time of year, especially those produced locally that I can store for months in my cellar, it takes about 5 minutes to prepare, mostly pealing the apples, it can cook at the same time as a main dish and it warms the kitchen (which is very cold at this time of the year). The recipe for the crumble cover is quite simple: mix 50g of melted butter, 75g of brown sugar, four tablespoons of flour and as much cinamon as you like with a fork then your finger. Cook at a low heat for 30 to 45 minutes, until the crumble cover is hard enough. Usually, the dish just lasts the single meal!
