Limoncello and thyme collins

To make the limoncello, peel the lemons removing as much white pith as possible, then put the peel into the vodka with the thyme (if using) and put in a dark place for two weeks, shaking the bottle daily.

Put the sugar in a pan with 300ml water and heat until the sugar dissolves and you’re left with a syrup.

Strain the vodka to remove the lemon peel and thyme and then pour into a sterilised bottle with the sugar syrup. Leave to infuse for a few hours or overnight.

When you’re ready to make the cocktail, put the limoncello (25ml) and gin into a glass, fill with ice, then top with soda and garnish with a sprig of thyme and a lemon slice.
