Some of the Royal Family’s much-loved treats are things you can easily pick up at a shop, like the late Queen Elizabeth’s beloved Bendicks Bittermints. However, there are others which are homemade and rather intriguing, including the "secret drink" she and her fellow royals would apparently take with them on their travels in the UK and beyond.
Batches of it were made once a month in the palace kitchens and former royal chef Darren McGrady unveiled the recipe on his YouTube channel last year. He explained that they re-used the royals’ empty tonic bottles to store this beverage, which is known as Lemon Refresher.
