TK Red Lemonade, a phenomenon that exists only in Ireland, is synonymous with farmer's lunches and dodgy drinks mixers. It tastes just like normal lemonade but with an extra kick of enigmatic artificial sweetener that leaves you confused more than quenched ("is that lemonade mixed with… some decaying cola candies?"). It's a taste that harkens back to childhood birthday parties or that night you drank 'Jameson and Red' and ended up at a rave in a garden center.
There's an urban myth that Red Lemonade was banned in the European Union due to its color additive being carcinogenic, and in the weeks leading up to Halloween it's sometimes relabeled as 'Witches Brew.' And yet this drink is often listed as one of the things Irish ex-pats miss the most about Ireland, and to them I would say: exactly how poor was your diet?
