1/2C (4 oz) (115 gr)butter, ice and cut into small cubes
1C (3.50 oz) (100 gr)old fashioned rolled oats
For the filling:
5C (1.30 lbs) (600 gr)sliced apples, peeled and
1/4C (1.70 oz) (50 gr)granulated white sugar
2tbsp (0.50 oz) (15 gr)all purpouse flour
2tbspcornstarch
1/2tspground cinnamon
1/4tspground nutmeg
1/4tspground ginger
Instructions
Preheat the oven to 340ºF (170ºC) and grease a 8 or 9 inches (20 to 22 cm) square or circular baking pan with a little butter.
For the topping:
In a medium bowl, mix the flour, brown sugar, ground cinnamon and salt. Then, add in the cold butter in small cubes and mix with a fork (without using your hands so that the butter does not melt) so that everything is integrated and balls are formed, like a crumble. This whole process can also be done in a food processor, or with a small mixer (nutribullet or ninja type). Then add the oats and mix using a rubber spatula. If it will not be used immediately, put it in the fridge to keep the butter cold.
For the filling:
In a large bowl mix the apples, sugar, flour, cornstarch, cinnamon, nutmeg and ginger until the apples are well coated with this mixture. Place the apples in the buttered pan.
Remove the topping from the fridge and place on top of the apples. Bake at 340ºF (170ºC) for 40 to 50 minutes or until the crumble begins to brown on top and the apple juices are bubbling on the sides.
Remove from the oven and let cool slightly on a cooling rack before serving so it does not burn.
