Muscat raisins in Amsterdam

At De Kaaskamer in the Jordaan in Amsterdam there was a crate of raisined grapes at the counter.  While I was paying for our 3 year old kaas with cloves, old kaas with coriander, and rosemary sausages, the woman who runs the shop invited me to try one.  Unbelievable.  Moist, chewy, super-sweet red Muscat.
