Add in the lychees, gently stirring and pressing on the fruit.
Let the syrup reduce and thicken. Stir occasionally until the mixture will lightly coat the back of a spoon. It will have a similar consistency to that of maple syrup.
Cool slightly, then pour through a sieve into a clean glass jar. The lychee chunks can be eaten or discarded.
Use to flavour drinks or as a topping for desserts.
Store this syrup in the fridge for up to one week.
