Wash mulberries gently in cold water and strain off all water.
Place all ingredients in the pan and place over low-medium heat. Stir until sugar has dissolved.
Bring to a boil and boil for 5 minutes, stirring occasionally. At the 2 or 3 minute mark, mash the mulberries with a potato masher. Adjust the temperature as necessary to maintain a steady boil.
Once cooked, pour the mixture through a fine mesh strainer. Use a metal spoon to push down on the fruit and ensure all syrup moves through the strainer. Discard the fruit and bottle the mulberry syrup.
Notes
Storing: Bottle the syrup immediately, allow to cool and then store in fridge (or on pantry shelf until opened if you follow your own canning processes).
