Blueberry Jam
Description
A simple way to make preserves ahead of time. Blueberries take well to canning. They make excellent jam. But for this, blueberries need to be cooked for a long time. The longer they cook, the more moisture evaporates from them, so the jam will be thicker. Jars keep for up to a year in a cool place.
