Golden berries (physalis peruviana) have a lovely mild tart flavour and are supposed to be very good for you!
You can read this article The Health Benefits of Golden Berries from the Global Healing Centre. It mentions Vitamin A, antioxidants, helping balance blood sugars and various other health benefits.
They’re like sultanas in that they’re dried and a similar size, but I think they taste more interesting and delicious!!! And so golden and pretty!! 🙂
