Ice lollies are a traditional summer favourite in Britain as they are in North America. Sold from ice cream vans patrolling the streets and found in the freezer section at delis and supermarkets, they are easy to make at home and healthier if made with less sugar. Flavours are perhaps not as exotic as Mexican paletas but are enticing nonetheless when made with superb local produce purchased at the farmers markets that seem to be springing-up everywhere.
For a more adult version of these refreshing watermelon ice lollies add a splash of vodka to the mixture. For a more child-friendly flavour that visually resembles the watermelon from whence the ice lollies came, add a handful of chocolate chips and omit the lemon or lime juice.
Caroline & Robin Weir's recipe as published in their 'Ice Creams, Sorbets & Gelati' was the starting point for this recipe. The inspiration for the vodka came from a watermelon and vodka granita I've had (more than once) at Jacob Kenedy's fabulous Bocca di Lupo restaurant in London. The idea for the chocolate chips came from I don't know where, probably something read or remembered from a long-ago trip to Italy. —olinsloan
