  • Variation:
  • 4 cups of blackberry juice (36 oz of blackberries made 2 cups of juice for me.  So about 72 oz of blackberries.  That is 6-7 of the 12 oz containers.)
  • 1/2 cup white sugar
  • 1 green and 1 red jalapeno minced
  • 3 1/2 cups white sugar
  • 1 box sure-jell pectin
  • 1/2 teaspoon butter
  • Makes about 10 – 12 half pint jars
  • 2 packages powdered pectin
  • 3 tablespoons cornstarch
  • 1 cup white sugar
  • 8 cups smashed blackberries ( I used a potato masher)
  • 6 peppers, minced
  • 7 cups white sugar

Step 1

Fill water canner half way with water and bring to a simmer.  Sterilize your jars and lids and keep them warm for when you fill to prevent the jars from breaking.

Mix Sure Jell packet and 1/2 cup sugar in a small bowl and set aside.
Crush your black berries one layer at a time in a mixing bowl with the potato masher. You don’t want to mash them so much it becomes think to where there isn’t juice. Just enough to extract the juice.

Place your cheese cloth (You will need 4 packages of cheese cloth or a roll of it.  I found these in the automotive section in Wal-mart) in another bowl and pour the blackberries onto it.

 Tie up the corners (Or pull them up and twist them) and allow the juice to drip through into the bowl. (I use my glass 2 measuring cup) You can squeeze gently if you want to, but do not squeeze it so the berries get to compacted in the cheese cloth or it is hard for the juice to come through. This process can be tedious and take a while.

Measure exactly 4 cups of juice and pour into a sauce pan.

Note: you can rinse your cheese cloth out a few times and squeeze out excess water and reuse. You don’t want to do this more than twice or you might get some of the fabric in the juice.

Mix the black berry juice, pectin mixture, the red and green jalapeno, and butter into your sauce pan and bring to a rolling boil on high heat that doesn’t stop boiling when you stir it.  Stir in remaining sugar and return to a boil.  Boil for 1 minute stirring constantly.  Remove from heat and skim off any foam in the pan.

To make sure that the jelly is of the right consistency, place a small saucer in the freezer.  Remove, once cold, and put a small amount of jelly on the plate.  Run your finger or spoon through it and if it doesn’t flow back into the other liquid then your set!

Fill jars up to 1/4 inch from the rim.  Wipe off the brims of the jars and place the lids and rings on the jars.  Put the jars on the rack in your water canner and lower into the water.  Process for 5 minutes.  Remove the jars from the water and let cool on a towel.  Once the jars are cool, gently press on the lids to make sure they don’t pop back.  If they do they aren’t sealed.

Mix the pectin and cornstarch with 1 cup of sugar in a bowl. Stir the blackberries, pectin mixture and peppers in a saucepan. Bring to boil for 1 full minute. Add the 7 cups sugar and return to a rolling boil until the sugar has fully dissolved, about 1-3 minutes Remove from heat.
Ladle into sterile jars and seal them in a hot water bath for 15 minutes.
