Cook the apples and water in a pan over low heat until soft, about 20 minutes. Rub through a food mill.
Add the sugar, cider vinegar, and cinnamon, mixing well. Put mixture in a heavy roaster pan, uncovered, and cook in a preheated 375° oven for approximately 2 1/2 hours, stirring every 15 minutes with a wooden spoon. The Apple Butter is thick enough when you can put 2 tablespoons of the mixture on a saucer and turn it upside down without it dropping off. Ladle into hot sterilized pint or quart jars and seal.
"I must say this is the best recipe software I have ever owned."
"Your DVO cookbook software saves me time and money!"
"I saw lots of recipe software for PC computers but I was having a hard time finding really good mac recipe software. I'm so glad I discovered Cook'n! It's so nice to have all my recipes in a computer recipe organizer. Cook'n has saved me so much time with meal planning and the recipe nutrition calculator is amazing!!!
My favorite is the Cook'n Recipe App.
