I tried my hand at canning a few years ago and have to say that it was a lot of work just keeping the little kids away from the boiling pots and hot jars. I was able to get some frozen berries from Meijer with coupons and thought I'd try this method of making jam. It literally took 5 minutes to do and cost about less than $5 to make six jars. One jar of blackberry this size would price at about $3.50. This jam will taste great in Kiflis.
6 cups smashed berries
1 1/2 cups sugar (more or less to taste)
1 package of freezer jam pectin
First, mix together the sugar and pectin. Add smashed berries and stir for 3 minutes. Ladle into jars and seal. Let sit for 5 minutes before putting into the freezer.
