Tri-Berry Jam

My mother-in-law and I dreamed up this jam after we'd been picking blueberries one day. She wondered if blueberries, raspberries and strawberries would taste good together. So she made a test batch—and we quickly learned that they definitely did! Then I came up with my own version of the jam. I preserve everything from our garden! —Karen Maerkle, Baltic, Connecticut

    I did 1.5x the recipe and used 9 cups of sugar. It was still too sweet, so next time I'll try even less. I used frozen fruit that were slightly thawed. Great to make year round!

    Do you have to thaw the berries before starting jam?

    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!

    This was my first attempt at canning and this jam turned out fabulous! I gave a bunch of jars away and everyone asked me for more. Even my picky grandfather said it was the best he's ever had. Will be a recipe I will be making every year!
