Easy Apple Crumble

I am a beginner baker. And I recently came across this recipe. It is simple, different and very delicious.
The recipe is from Nags cooking and me.I blindly followed her recipe for the crumble.
Here is the Original recipe.

 This is the simplest way you can make apple crumble. Go ahead, try it.

Ingredients:

Apples - 500gm (about 2-3 medium-sized apples)

Wheat flour / atta - 1 cup

Salted butter - 100gm + a bit for greasing

Sugar - 2tbsp + 2 tbsp

Salt - a pinch

Lemon juice - a few drops (optional)

Cinnamom stick - 1 (optional)

Method:

1. Wash peel and chop the apples. Add a few drops of lemon juice to prevent browning. Mix in 2tbsp sugar and cook on a low fire until soft and mushy. Set aside to cool.

2. Mix salt and 2tbsp sugar with the flour. Lightly mix in the butter without kneading until you get a mixture that resembles bread crumbs.

3. Grease a pie dish/cake tray with butter. Lay the cooked apples evenly. Add the flour mixture evenly on top and press down gently. Sprinkle sugar on top.

4. Bake in a pre-heated oven at 180C for 25-30 mins.
