What I am about to show you is the basic way to make jelly. Just remember to check the portions of ingredients for the TYPE of jelly you want to make. There is an insert inside each box of pectin. There will be canning instructions and recipes on the insert so not to worry. You can always get on the computer and "search" the type you want to make.
Hope this helps make you brave enough to try canning. It is a lot of work....not difficult. Keep things clean and hot and you will be OK.
