What is freezer jam? So called because it keeps so well in the freezer, it is, according to Clay and Zach at The Bitten Word, the perfect way to preserve summer fruit without distorting its flavor.
"Making freezer jam is delicious and incredibly easy. With traditional jam, you thicken the fruit by cooking it and boiling it down. In making freezer jam, however, you use pectin to thicken. And since you don't cook the fruit, the jam tastes intensely like the fresh fruit itself."
