So would I - out of curiosity. It would have to be exceptionally good to have it a second time.
The only savoury ice that I've tasted is a tomato sorbet from a 1930s recipe. I used it two or three times as a first course but you could serve it as a palate cleanser between courses as sorbets used to be served. It's interesting and refreshing.
Don’t look for the light at the end of the tunnel. Stomp along and switch the bl**dy thing on yourself.
