Apple crumble with orange flavours

This is a bit of an overhaul on apple crumble (I am a bit obsessed with orange flavour)

• 1 kg apples
• zest and juice of 2 oranges (or 1 depending on the size and your personal preference)
• 250 g oats
• 200 g plain flour
• 4 tsp cinnamon
• 200 g butter
• 200 g light muscovado sugar

Peel, core and chop the apples and place into a buttered baking dish (I like to use purex as that way you can see the food), and add the orange stuff. Mix everything else except the sugar together, then stir in the sugar. Sprinkle over the apple and bake for about 30 mins at 170 degrees Celsius (depending on the the surface area to volume ratio of the dish).
