Blend the peaches into small pieces in a food processor.

Place the peaches, the sugar and the orange juice in a pot.

Let them boil for a couple of minutes over strong heat and then turn the heat down and simmer for about 20 minutes (perform the test with the plate) stirring from time to time so that it doesn't stick.

Finally add the drops of lemon juice and when it cools store in glass jars in the fridge.
