Juniper berries is what makes gin, well, ginny. This mocktail uses juniper berries to give an aroma and taste of gin without the alcohol. If you want a No Gin and Tonic, substitute tonic water for the sparkling or mineral water.
Take one juniper berry and rub the rim of each serving glass, then add the rubbed berry to the rest of the juniper berries in a mortar. Crush the berries well with a pestle.
Add crushed juniper berries to a pitcher. Squeeze half a lime over top and add squeezed lime to the pitcher. Top with sparkling or mineral water. Let sit for 5 minutes.
Fill serving glasses with ice and pour drink over. Garnish with lime slice, if desired. Serve immediately.
