Gin and tonic tastes a million times better with home-grown lemons. Trust me, I’ve tried it, so have the neighbours! So, finding my four-foot lemon tree dripping with fruit when I arrived at my Costa Brava villa this week was a real treat, at least for me and the wife, who enjoy a sundowner. The children – three year old Clemence, six year old Harry and nine year old Maddy – were more excited about slurping away on their all-time favourite drink, chocolate flavoured Cacaolat, which you don’t get in the UK. I think the youngest can see off a carton in under 10 seconds now.
