Optional: pinch of salt or ¼ teaspoon vanilla extract for flavor depth
Instructions
Add the chopped mango to a saucepan over medium heat. Cook for 5–7 minutes until soft, stirring occasionally. Mash mango with a spoon or potato masher.
Add the sugar and lemon juice (and salt or vanilla if using). Stir well.
Simmer the mixture over low heat for 15–20 minutes, stirring often, until thickened and jam-like. Jam is done when it holds its shape on a cold spoon or plate.
Let jam cool completely. Transfer to a clean jar and store in the fridge.
