Reviews for Tri-Berry Jam
"PLEASE, WHAT IS THE PROCESSING?DO YOU MEAN PUT THE CAPPED JARS OF JAM IN BOILING WATER.? HAVE A PIECE OF WOOD IN PAN SO JARS DO NOT BREAK/"
"Can this recipe be cut in half???"
"@Sambow96 - your processing time begins once the water is boiling, so no, it's technically not necessary to put the filled jars into a hot water bath that is already boiling. I begin heating my water while making my jam. It's definitely coming to a boil by the time I'm ready to fill the jars, but I wouldn't say it's at the "constant boiling" point you need to maintain while processing when I first put the jars in. You definitely want to start heating your water before you begin to make your jam --- I don't put jars of hot jam into a pot of cool water and then bring it to a boil."
"I made this jam for Christmas gift giving. I called it Very Merry Berry Jam and decorated the jars with holly fabric covers. Everyone loved the blend of berries & the color of the jam is beautiful. One guy said he ate the jam every single morning until it was gone. I got my empty jars back from a neighbor with a note inside that said "more, please!". Best compliments on Xmas gifts ever. Thank you TOH and Karen!"
