To make this jelly you will need a food puree-r. Start with a large bowl of blueberries. Take a small amount of the blueberries and put them into a separate bowl and mash them up. You don't want to puree all the blueberries. Dump the rest of the blueberries into the puree and start pureeing them into the bowl with the smashed blueberries in it. Turn the handle a few turns and then add the grapes into the puree-r with the blueberries. Puree the rest of the of the grapes and blueberries until they are all pureed. After all the grapes and blueberries are pureed stir them up in the bowl and then pour the pureed mixture into a pan over medium heat. Stir the mixture as it comes to a boil. Add enough sugar to bring the mixture to the preferred sweetness and let the mixture come to a boil again. Be careful not to add to much sugar because the grape blueberry mixture is naturally very sweet. Next you will add pectin. The pectin will help the mixture thicken into jelly. After you've added the pectin let the mixture simmer and come to a boil then you will be ready to put the jelly into jars. Fill the jars while the jelly is still boiling. It's important not to completely fill the jars. Leave about one quarter of an inch or a little more of space when you are filling the jars. Before putting the lids on the jars make sure there isn't any jelly on the rims so that the lids close firmly. Next start boiling some water in a large pot and put the jelly jars into the boiling water. Let the jars of jelly boil for about ten minutes and then take them out and let them cool. Once they cool they will be thickened up and ready to eat.
