(I got excited about my new to me fruit bowls and took a photo well before the fruit was attacked)
My mum makes the best crumble. When I was about 16 she taught me how and I have been making it since. It is a matter of ratios and you can add pretty much any fruit that tastes good cooked. Take it from me, tamarillos* are good here.
For the ½ cup version, you will need:
Raw fruit (about 6 apples or maybe 4 apples and some tamarillos)**
½ cup flour
½ cup rolled oats
½ cup sugar (half brown, half white)
Preheat oven to 180 degrees celcious.
Peel, core and slice fruit. Place in an oven proof dish that fits the fruit, say 20cm round.. If the fruit is tart add sugar to sweeten.
Mix together dry ingredients. Grate the butter and add to the dry ingredients. Saving a little to sprinkle over the top.
Bake for about 30 minutes or until fruit is cooked.
This version serves about 4-5. If you have more people to feed, increase the quantities i.e ¾ cup of dry ingredients and more fruit.
*If you are wondering about the tamarillos, they are the purple egg shaped fruit just below the mini pumpkin.
**Harder fruit like quince, taste great but will need to be precooked.
