Mom'S Best Ever Apple Butter - cooking recipe

Ingredients

1/2 bushel apples (I like Winesap best, but Jonathan also good)
5 lb. sugar
1 small bottle oil of cinnamon (buy at drug store)
2 c. dark brown sugar
2 Tbsp. apple pie spice and 1 Tbsp. nutmeg
2 Tbsp. ground cinnamon

Preparation

Slice up apples; core, skins, seeds and all.
Layer in large size pressure cooker or I use turkey roasters for oven method.
My grandmother and mother did this on top of stove using big pressure cooker.
I adapted it to my ovens and use 2 turkey roasters for 1/2 bushel of apples.
One will work with 1/4 bushel.
Layer apples, alternating with the 5 pounds of regular sugar.
