Delicious and easy.
4 cups blackberries
4 cups sugar
2 teaspoons fresh lemon juice
Combine all ingredients in a large pot. Once the berries soften, crush them with a potato masher (or whatever works for you).
Bring to a boil. Reduce to a simmer.
While simmering continuously stir for 10 minutes.
Test the set by dipping a metal spoon in the jam. Set the spoon in the freezer for 5 minutes. If you are happy with the consistency, ladle into sterilized jars. Water bath for 10 minutes.

Looks delicious! I love blackberries! Found you on the Clever Chicks Blog Hop.
Hi Tina! Thanks for checking out my blog. I love the blog hop. So many interesting things in one place.
This jam is delicious and it was super easy. Let me know if you try it. 🙂
I just made my first batch of blackberry jam from our home grown berries. I love how simple this recipe is.
I made your recipe and it came out so delicious I like the no pectin just plain and simple everyone enjoyed it and I’m making my second double batch this weekend thank you so much
Looks so easy and good! How many 4oz jars does this recipe make?
I made your jam this weekend but I am unsure how to store it.
Help please.
They are shelf stable until opened. 🙂
Made this jam recipe. Super easy. Boiled the jars/lids for 10 minutes. Then filled to 1/4 inch from the top. Attached the lids and placed them in a water bath for 10 minutes. Licked the pan when I was all done and it tasted great! Can’t wait to use the blackberries we picked as jam over the next few months. This recipe filled five 8 oz ball jars.
This is amazingly delicious. Only question I have is how can you make it with less seeds?
