Made this today as I had so many berries from my garden. I used strawberries, rasberries, blueberries and marionberries. Followed the recipe except for a few minor steps - didn't mash the berries, cooking them seemed to do that just fine and I like bits of fruit in my jams and didn't use a pressure canner - used the hot water bath method and that worked fine. Love the flavor and appearance and will be making more of this when next I have a harvest big enough.
Very tasty jam, mine didn't set up properly, I haven't made a no pectin jam before this one, so it could be inexperience. I didn't have a lot of blueberries or any blackberries, so used the same qty, but used extra strawberries and a bit of apple as well.
Really good. None of the berries overpower the others.<br/><br/>I boiled it for the 30 minutes and I think that is a little bit too long. I noticed thickening at about 20 minutes--and I should have stopped then.<br/><br/>The jam is a bit strong/thick. Otherwise, I would (and have) recommended this.
