I did some research and found this recipe. I am including the summary.
If you are canning this recipe, get your water bath canner ready! Place the 3 cups of dandelion liquid into a large pan. Add 2 TBS of lemon juice and 1 box of pectin. Bring all of this to a boil. Add 4 1/2 cups of sugar and bring the mixture back to a boil. Stir the mixture constantly and continue to boil for 2 minutes. Remove the pan from the heat, skim off any foam using a slotted spoon, and fill canning jars leaving a 1/4 inch headspace. Process for 10 minutes. This recipe made just about 6 half pints.
