1 peppercorn swish (or sprig of tarragon or rosemary)
Directions
Make the makrut lime-infused gin. Coarsely chop the lime leaves and combine with the dry gin. Store covered in the fridge for 24 hours. Strain out the leaves using a tea strainer or colander.
Make the Costa Blanca: Place the blood orange round into the bottom of a large stemless wineglass. Add the gin, lots of ice and tonic. Finish by sliding the peppercorn swish against the inside of the glass. And serve.
