1 1/2shots of reposado tequilaor any good quality blanco
juice of half a ruby grape fruit
1/2shot of agave syrup or sugar syrup
about 75ml club soda
a squirt of fresh lime juiceoptional
Instructions
Mix the grapefruit juice, tequila and sugar syrup until well mixed.
Pour over a tall glass filled with ice and top up with soda water. You could add a squirt of lime juice which is nice and I did, and you could also rim the glass with salt.
Notes
If you are wanting to reduce your sugar intake, simply leave the sugar out. Its less sweet but still delicious.
