Maybe they should try serving actual ice cream instead of Guar Gum Surprise. :)
They don’t claim it is ice cream on the menu. For example, they don’t have ice cream cones or ice cream sandwiches, but “cones” and “DQ sandwiches.” It is actually labeled “ice milk” on the soft serve container behind the counter.
There’s always Partially Gelatinated Milk Byproduct down at the Krusty Burger.
