This brings back some great memories. My mom made fantastic home made jams. All through my childhood family members and friends would clamor for her jams she made at Christmas.
This year I finally got her to give me her recipe....it was basically the recipe on the packet of Sure Jell :-/ She did note that the important part was to by fresh fruits for the jam and not frozen so I guess there was that. Regardless it was a huge let down to know the secret was the recipe on the box of pectin that was $.50 each.
