Ingredients

50ml Pentire
25ml Grapefruit syrup*
25ml Lime juice 25ml
Fresh grapefruit juice
Soda to taste
Pinch of Cornish sea salt

*Equal parts caster sugar and fresh grapefruit juice (as a sugar alternative you can use honey or agave).

Garnish: Thin wheel of lime

Method

Fill a highball glass with ice cubes, measure in the Pentire, grapefruit syrup, grapefruit juice, lime juice and a pinch of salt and top up with soda. Stir and garnish with the thin wheel of lime. *400g Caster sugar 200ml Fresh grapefruit juice, strained. Combine two-parts caster sugar to one-part juice to, as it is a little thicker and takes up less volume in the drink. Put the sugar and juice in a pan and set over a gentle heat. Be careful – the mixture shouldn’t simmer as this will introduce flavour into the syrup. You will notice that the sugar will dissolve and the syrup will clarify. Once it gets to this point, take it off the heat. Store in the fridge for up to 2–3 weeks.
