We started buying these sweets a few years ago now in a deli in Mayfair then that closed. Then we found them in Selfridges. I think you can still buy them there.
They are available on Amazon if you don’t mind their dodgy ethics and a friend of mine just brought a load to Boardmasters festival and we were reminded once again how amazing these plant based sweets actually are.
My favourite of all the wiggly worms and gummy bears are tropical wonder which for vegan I can promise you taste absolutely magnificent just like the fruit salad gummy’s of old my Nan who is also a fan assures me.
Good luck finding them and I recommend buying in bulk.
Buyer at Waitrose or Marks and Spencer if you are reading this, way better option than Candy Kittens and Percy Pigs you currently stock.
