I have heard that in Japan people eat some kind of salty ice cream. Is it true? If it is true, does anyone know the name of the dish or how to prepare it?
I've made miso caramel ice cream, salted caramel ice cream is a popular flavor in the Seattle area, and an uncle of mine tried an olive-oil and salt gelato at one of Mario Batali's restaurants, and I've had a salted peanut butter ice cream at a restaurant a few years back. There wasn't much adjustment required to accommodate the salt; unless you're using so much as to be unpalatable, it won't dramatically change freezing temperature or texture. If you're using less sugar, that can be a factor, but there are other coping strategies for that (alcohol, etc).
