Jams & Jellies
diced fruit (peeled if desired)
. Add fruit and sugar to a large bowl. Mash with a fork to combine and let sit for 10 minutes. Transfer fruit mixture to a medium heavy-bottom pot. Add lemon juice and salt.
Bring mixture to a boil, then reduce to a simmer over medium-low heat. Cook, stirring occasionally, until jam coats back of a spoon, 15 to 20 minutes. (Jam will thicken more as it cools.)
Transfer hot jam to clean glass jars and screw on lid. Allow jars to cool completely, then transfer to fridge.
Store jam in the fridge for three weeks or up to six months in the freeze.
