Christina's Notes
Bubbles Will Change: When the bubbles start slowing down and looking thick, the jam is almost done. Make sure you stir often to avoid burning.
Thickens as it Cools: This jam will thicken quite a bit after it cools down to room temperature.
Smoother Jam: If you want a smoother jam, skim any foam and mash the berries even more.
