1 Granny Smith apple
100ml Lemon juice
120ml Hierbas de las Dunas
80ml Tequila
60ml Sugar water (simple syrup, 1:1)
Ice cubes

Peel and chop the apple and remove the core.

Blend all ingredients except the ice cubs in a blender. Add a handful of ice cubs and grind the mix. Run a lime wedge around the outside of the rim of a glass and roll the rim in sea salt, samphire salt or algae salt. Pour everything in the glass and serve with a straw.
