The French call it Pamplemousse, while bartenders often refer to it affectionately as ‘mousse juice’ and it sits aside St Germain and fresh Ginger in the realms of ‘bartenders ketchup’ (an ingredient that can reliably improve just about any cocktail).

Ruby Grapefruit Liqueur is not only juicy and fruit but strikes a great balanced between tart and sweet. Made from ripe, ruby grapefruit, this liqueur can be drunk with a bit of soda water and ice, but is even tastier when you mix it into cocktails.

Use 1oz of homemade Ruby Grapefruit Liqueur with 1.5oz Bourbon and 0.5oz Honey Syrup in a Brown Derby or the sdame amount in a Sunset Strip, which also requires 1.5oz Bourbon and an 1oz of Aperol.
