Refrigerator Peach Jam is a late summer standby. It's a simple, sweet preserve with a hint of cinnamon. A small-batch, one jar at a time recipe I love.
To a large saucepan add sliced peaches, sugar, water, and cinnamon stick. Bring to a boil; add butter and reduce heat to medium.
Continue to simmer the peaches on medium to medium-high heat, removing foam from the surface as needed until the peaches are soft, most of the liquid has evaporated and the jam has thickened. About 20-30 minutes. During this process, I like to use a potato masher to further break down the peaches. The back of a spoon works well too.
Ladle jam into glass refrigerator containers. The jam will keep in the refrigerator for up to 2 weeks.
