Canned apple sauce

I warmed my jars in my oven. My lids in a pot of water set to low heat and got the water boiling in my canner.  I quartered the apples and put them in my juicer until soft.  I drained the juice and froze it in ice cream buckets.   We ran the mushed up apples through the food mill then once I filled 1/2 my pot (10-12 cups) I added 1 cup sugar and a sprinkle of cinnamon and warmed it on medium heat then filled my 7 500 ml jars and processed them in a water bath for 20 minutes.
