3 1/2 Pecks = 11 Quarts...and I ended up over-filling the jars and having a canning disaster so let's call it 12 quarts per 3 pecks?
Each quart took three ladel fulls of hot "juice"...probably 2 or 2-1/2 with fewer apples.
I also found making the Thanksgiving pies, I didn't use all the juice I made to can them with, either discarding some or mixing freshly cut apples in with a jar of canned ones.
Thumbs up on the Norpro apple peeler! Made my work much faster!!!
The completed product...I could can 7 bottles, I wasn't prepared to do another batch that night -- plus as soon as I started removing jars from the water bath I could tell they hadn't sealed right. So the next day I repacked them in plastic and put them in Mom's freezer.
