In a saucepan, add chopped mango and sugar. Cook on medium heat while mashing the mango until you get a thick jam-like consistency for 15-20 minutes. Stir in the lime juice and cook for another 5 minutes.
Let the jam cool completely before transferring to a jar. The jam will continue to thicken over the next 24-48 hours. Use mango jam on buttered bread, yogurt, pancakes, even ice cream. Enjoy!
