“Do you fear sour?” the fruit vendor asked when I requested a taste of this mysterious red fruit. He also, thankfully, told me its name, giving me an look that managed to combine “extremely bored” with “you are an idiot.”

Well, we just don’t have red bayberries where I come from.

They are very sour, but fascinating, with a taste a lot like redcurrants. No need to peel – just eat your way through the outside layer, knobbly and waxy but very thin.

Available from a cart probably within 100 feet of you!
