Yes, it's true! Up until the end of Valentine's week, you can buy beetroot infused with chocolate and mint flavours. The people at Love Beetroot have also revealed that beetroot contains tryptophan, which is also found in chocolate, and gives people a 'sense of wellbeing'. They also say that the ancient Romans considered beetroot an aphrodisiac *raises eyebrow*.
You can find it in Tesco stores, priced at £1.25 for 180g. I haven't managed to get out and try any of it yet, but I will. If you do, let me know what it's like!
In the meantime, check out the Love Beetroot website for more information and recipes.
