So I finally got around to trying this and... it tastes exactly like a sweet potato. A cold, creamy sweet potato.

I am not sure what purple is supposed to taste like though.

It is pretty good tbf but as World's Most Boring Furry I'd rather just have a vanilla cone.

@sequentialsnep ok, so I can remove it from my to-try list; was afraid of that and also slightly relieved. At least it doesnโ€™t taste of purple.
@evi
Just a taste won't hurt! Just have a cup of tea mixed with coffee on the side to wash away the potato taste XD
@sequentialsnep probably would. Canโ€™t be worse than the lingonberry soda from Ikea.
