Add cherries, sugar, lemon juice, lemon zest, and salt to a large saucepan. Stir to combine.

Bring mixture to a simmer over medium heat. Cook for 25–35 minutes, stirring occasionally, until cherries break down and the jam thickens.

Use the back of a spoon or potato masher to gently crush the fruit as it cooks for a smoother texture.

To test consistency, place a small spoonful on a chilled plate. If it wrinkles slightly when pushed, the jam is ready.

Remove from heat and let cool slightly. The jam will continue to thicken as it cools.

Transfer to jars and refrigerate. Enjoy!
