Gooseberry and lime lemonade

Press the juice out of the limes. Pour the lime juice, gooseberries and water in a pan and bring to a boil. Simmer over low heat for about 15 minutes. Strain through a sieve, using a spoon to press all of the juice out of the berries. Put the mixture back on the stove and add the sugar. Cook for about 20 minutes more. Cool it! When serving, add some mint leaves and dilute with sparkling water.
