Peel the papaya and remove the seeds. Cut them into thin strips. You can also use a mandoline slicer to make uniform slices. Soak the papaya in cold water for 10-15 minutes.
Combine sugar, water, and salt in a saucepan. Place it on heat and bring it to a rolling boil. Simmer for 1-2 minutes until the sugar dissolves.
Drain all the water from the papaya and add it to the sugar syrup. Cover and simmer for 15-20 minutes or until the papaya is fully cooked.
Add lemon juice and let it cook uncovered for 1-2 minutes so that the chutney can thicken. Turn off the heat and let it cool down completely. Chill before serving.
Notes
Cut the papaya into thin, uniform strips to ensure even cooking and a consistent texture in the chutney.
Cook the papaya strips in the sugar syrup over low to medium heat to prevent them from breaking apart.
