This is a wonderful Beverly Nye recipe for canning your own pie filling. I use it for apples but I have friends who have used it with good success for peaches.
I've written it out just as it came from Beverly's cookbook back in the 70s so from here on out, these are Beverly's words...
Canned Pie Filling
Combine in large kettle:
4 cups sugar
1 cup cornstarch
3 tsp. cinnamon
1 tsp. nutmeg
1 tsp. salt
Add: 10 cups water
Cook until thickened and add: 3 T. lemon juice
Fill canning jars 1/3 full of sauce. Peel and slice apples into jars, smooshing down into the sauce until the jar is full.
Put on hot lids and process in boiling water bath for 20 minutes. Fills 7 quart jars.
When you want to make a pie, just roll out the crust, pour in the filling, dot with butter, and cover with the top crust. Bake at 400 degrees for 40-50 minutes.
You can also substitute other fruits such as peaches or cherries. You may want to vary the spices a little. Sometimes I (Beverly) use a little more cinnamon and nutmeg with apples.
