Grape Jam


Posted by request. I haven't made grape jam in years (since my kids were small). Unfortunately, i never wrote down how much this recipe makes, i remember it did make a lot (8-10 cups???)

Steps


Remove the skins from the pulp and set them aside.
Place grape pulp in stainless jelly pot with water.
Bring to boil and simmer 5 minutes.
Strain to remove the seeds.
Chop the skins and add to the cooked pulp.
Measure out 5 cups of the grape pulp mixture and return the pulp to jelly pot.
Add sugar and butter.
Heat on medium heat until sugar is melted , then adjust to high heat.
Heat and stir to full rolling boil that will not stop.
Add 1 pouch certo and return to full rolling boil at high heat.
Boil exactly one minute stirring constantly.
Fill jars to 1 / 8 inch from the top.
Seal with lids.
Invert jars for 5 minutes.
