Put all ingredients in a small pan and warm over a medium heat, stirring initially to ensure sugar has dissolved.

As mixture comes to the boil, you will hear the cranberries burst. Once boiling, press cranberries to bottom or side of pan to help any that haven't popped do so and release the flavors.

Boil for 3-5mins then remove from heat and strain mixture into a bottle or other container.

The cordial can be mixed with hot or cold water, still or sparkling, on approx 1 part syrup to 5 parts water ratio.

Cordial will keep for a couple weeks in the refrigerator.

The leftover cranberry mixture after straining can be re-used as a jam if the pieces of ginger and orange rind are removed, again store in a box in the refrigerator.
