Though truth be told, THE best ice cream, I have EVER had, is made by a small ice cream shop in Holmes Beach, on the west side of Florida, called JOE'S EATS & SWEETS.
Nope, the best ice cream is UCONN Dairy Barn...in Storrs, CT.
Haagen-Daz is owned by Nestle as are Dreiers and Edy. Swiss, not American. Unilever owns Ben and Jerrys and Breiers. Unilever has dual headquarters in the U.K. and The Netherlands. The largest American owned ice cream producer is likely Texas based Blue Bell.
