How to Can Blackberry Jam

We may earn money or products from the companies mentioned in this post.

I love July/August in the Pacific Northwest for so many reasons, but one that is at the top of the list is because of all the blackberries. We are so fortunate to have blackberries growing wild. I try and pick them a few times a week to get a stock pile going. I freeze them to use throughout the year, but the majority of what I pick I use to make jam. I will usually make 2-3 batches, because I give some away to family and friends. I usually end up with enough jam to last us an entire year, and because the berries were free it makes it taste that much sweeter.

Making jam is super easy. If you haven’t canned before here are some of the basic supplies you will need:

Canning Jars with lids & bands (pint size)
5-Piece Home Canning Kit (you can make do without, but nice to have)
Canner with Rack, 21.5-Quart
Fox Run 3-Piece Stainless-Steel Chinois Set or small mesh strainer

Blackberry Jam Recipe: (makes 6 pint jars)

Sure jell
Sugar
lemon juice
Blackberries

The amounts of sugar, lemon juice and berries will be listed on the instructions in Sure Jell box. Follow directions and quantities exactly as directed to be sure you are canning the jam safely.

The first step is to get as much juice from the berries by using a food mill or some kind of strainer. My recipe called for 7 cups of mashed blackberries. I don’t like a lot of seeds in my jam so I used about 10 cups of blackberries and mashed them to get the juice. Once I had a little more then 5 cups of juice I added the mashed blackberries to the juice.
