The yield for our dandelion jelly recipe depends on the size of the jars used for canning. The recipe makes about 4 cups of jelly, which is enough to fill approximately four half-pint jars or two pint-sized jars. However, the yield may vary slightly depending on how much the jelly reduces during the cooking process and how much headspace is left in the jars. It's always a good idea to have a few extra jars on hand just in case you end up with more jelly than expected.
