Gaaaaanz earlier (in the 90s) there was once a banana ice cream. Stängeli. If I remember correctly, it even had the shape of a banana (or was that a rival product?) Anyway, I loved the banana Stängeli ice cream from Migros. It doesn't have to be banana-shaped, it would be fitting to create a banana-flavored Stängeli Rahm Glace variety.
I also miss the lemon cream ice cream, the one with the "lemon butterfly" on it. Would be so refreshing and enjoyable!!! ;-)
