Cut the half a lime into 4 pieces. Muddle together in the serving glass the 4 pieces of lime, the sugar cube and 3 of the fresh mint leaves. Add the De Kuyper Blackberry and half fill with crushed ice. Stir together and then fill the glass with more crushed ice.

A rich berry flavour combines beautifully with the tangy ness of the lime. Use limes that have lovely bright green skins so the colour can be seen through the glass and serve with a straw.

Garnish with the remaining sprig of mint and a fresh blackberry if desired.
