Peel peaches and chop into pieces (including pieces with stone in it).
Place peach pieces into a baking tray and sprinkle sugar over top.

The next day, the sugar will have dissolved leaving a syrup. Pour syrup into a saucepan and place the peach pieces which include the stone into the syrup.
Boil syrup for 10 minutes. Remove peach pieces with stones and discard.

Add salt and lemon juice and simmer for another 2-3 minutes.
Mash jam with a potato masher if jam is still too chunky.
Pour into a sterilised jar and seal.
