Place tea bags and prunes into a small glass bowl (or non-reactive heat-proof bowl) and just cover with boiling water. You don’t want an excess of steeping liquid as this will also be used to make the syrup.

Let steep for 5 minutes and remove the tea bags.

Place prunes, steeping liquid, and all remaining ingredients into a small pot and bring the liquid to a simmer.

Stirring occasionally, cook until liquid reduces to a syrup.

Remove from the heat and cool to room temperature.
