I am short on some frozen strawberries for the fruit pack and am wondering about using something like Strawberry jam.
I wouldn't. There's a ton of pectin in jams to make them jell up the way they do. If it's commercial jam I'm sure there's sorbate and other chemicals you don't want.
I used up a whole bunch of home made jelly and jam and made good wine that has all been drank up. Had no fruit so I used what I had. Mike
