Peel the apples and slice them into one inch cubes. They won't be perfectly the same, but slice them as uniformly as possible. Place them in a big bowl.
10 Large Granny Smith Apples
Now that the apples are ready, heat the oven to 350 F.
Coat the apples with lemon juice.
1 tbsp lemon juice
Coat them with melted butter.
6 tbsp unsalted butter
Add the brown sugar, white sugar, salt, and all the spices. Mix very well by tossing the apples over and over till all are coated.
1 cup brown sugar, ½ cup white sugar, 2 tsp cinnamon, ⅛ tsp salt, 1 pinch nutmeg, 1 pinch allspice, 1 pinch cloves, 1 pinch ground ginger, ***or to replace the pinches of spices use 1/4 tsp of pumpkin pie spice***
In a small bowl, whisk the water and the cornstarch. Pour it over the apples and toss again until all is well coated.
4 tbsp cornstarch, ½ cup water
Pour the entire apples mixture into your baking pan.
Place the baking pan into the oven, heated to 350 F. Bake for 30 minutes.
In 15 minutes toss the apples around.
At minute 30 toss the apples again, then increase the oven temp to 375 F and bake for an additional 20 minutes.
Be sure to toss the apples around one more time to ensure even baking and coating of the sauce all over the apples. Taste to ensure the texture is tender but with some firmness.
Once the time is up, remove from the oven. Mix the apples and sauce well. Let cool down before serving. Let the mixture cool down completely before using as a pie or turnover filling.
