Prepare water bath canner and get the jars & lids ready (be sure to know your basic canning safety). Need a water bath canner? We bought this set and it’s perfect for beginners!
Combine the peaches & sugar in a large non-reactive pot. Cook on medium heat allowing peach juices to release. Slowly bring to a boil and add lemon juice and vanilla.
Let the sauce cook over med-high heat for 15-20 mins stirring frequently until it looks syrupy. I use a hand blender at this stage to break up the peaches so it’s not chunky (be careful it can splatter & it’s hot)
Add the pectin and bring to a strong boil for 5 mins or so until it’s thick and shiny. (be sure to read your pectin instructions as they differ in method).
Remove the pot from the heat & ladle the jam into the prepared jars. Wipe the rims, apply the lids & rings and process in a boiling water bath canner for 10 mins (be sure to know your basic canning safety and adjust the time with altitude).
How to Blanch Peaches & Prepare Peaches: boil water then gently add peaches into the pot with a slotted spoon. Boil for 2-3 mins and immediately place into a bowl of cold water. Using a knife make a small cut across the skin then put knife aside. Peel off the skin with your hands and discard into compost. If the peaches are still hot run them under cold water to do this. You will need to change the cold water bowl every few batches to keep is cold.
I make jam on the same day that I can peach slices and use the pulp around the core as the bulk of my jam pulp. It’s easy to squish the pulp off the core and it’s a nice small size for the jam. I also add some whole peaches so it’ s not just the core pulp.
If you wish to just have a peach sauce omit the pectin entirely. This is a cheaper option and it’s wonderful on crepes, baked into sweet breads or put over pancakes etc.
