The bitter oil squeezed from the zest of citrus fruits adds an extra dimension to drinks, allowing the full flavour of the fruit to come through in the drink. For example Caipiroskas, and Mojitos benefit from the zesty bitterness of the lime oil mixed with crushed ice and sugar.

If you are making a classic Naked Vodka Martini a spray of lemon oil over the surface of the drink will add an extra zing to the drink. With a sharp knife, cut a slice of lemon zest ensuring that there is no white pith, and bend the zest back onto itself to allow the oil to spray out. Little pools of yellow lemon oil will skate over the surface, and with every sip, you will get a whoosh of lemon oil up your nose as the Martini hits your tongue – the perfect olfactory experience.
