is a bit problematic here in Israel according to the Chief Rabbinate's Kashrut Bulletin:
Locally-produced ice cream of all sorts is fine.
But certain imported products like the Karamel Sutra seem to be identified as "not in accordance with regulations". I do not know if that means the product is kosher but not imported as expected or some other problem.
Do they still boycott?
The Pals. don't like them much, either. Even though they sold out to Unilever.
