What time is ‘Pimm’s o’clock’ in the royal household? Invented in the 1840s, Pimm’s No.1 Cup is still an iconic British tipple served at garden parties, picnics, barbecues, sporting events and of course, Wimbledon. The secret recipe of gin infused with herbal botanicals, caramelised orange and warm spices is best served in a jug with friends, mixed with lemonade and served with fruit. The Queen apparently likes her Pimm’s with seven types of garnish: sliced oranges, cherries, lemons, strawberries, cucumber, mint and borage.
