Hello Gruffalo, I think Sue and Babayaga are right, it must be a misprint. I wouldn't translate it unless the client insists, or maybe put a description in parentheses. If it is indeed pana cotta, it means cooked cream, so the "Crème" is already superfluous.
I'm not sure a restaurant customer would find "cooked cream" very appetizing, maybe better to let the waiter explain, or find a better way of describing it.
I had it ages ago for dessert when having dinner with my brother-in-law's parents, who were from Turin. Every time I ate at their home it was a treat, his mother was such a wonderful cook. Off subject, but I stil remember how shocked I was to love something as unlikely sounding as veal with tuna fish sauce (vitello tonnato), even though my own Mom served all sorts of cuisine.
Memories aside, I think it's often served with fruit topping, like berries.
Re spelling, not sure if you should use the two-word or one-word version.
If you're hungry, maybe you should try some green tea ice cream:-)
