Make coconut clove sugar by combining coconut sugar and cloves in a bowl.
Mix well, then pour out onto a shallow plate.
Use a grapefruit wedge to rim your glass, then dip the rim in the coconut clove sugar.
Add ice to the glass and set aside.
Next combine the vodka, pomegranate juice, grapefruit juice and pinch of ground cloves in a shaker with ice.
Shake, then pour through a sieve into the sugar-rimmed glass.
Finish with the soda water and a sprinkle of pomegranate seeds.
