Start by preparing your jars and lids, making sure they are clean, sanitized and dry.
To a stock pot, add your diced peaches, pectin, and lemon juice. Mix well.
Bring to a rolling boil. Stirring frequently so it doesn’t burn. At this time you can mash your peaches. I prefer very little chunks.
It's important that it is at boiling point before adding your sugar. Add your sugar and bring to a rolling boil, that can’t be stirred down. Leave at a rolling boil for 2 minutes, stirring constantly. Remove from heat.
Fill each jar leaving a ¼ inch head space. Wipe down your rims, seal your jars, and it’s time for a 10 minute water bath. Let sit for 24 hours.
Enjoy! You'll never want to have store bought again.
