Tried the new Sweet purple potato flavour in the Hokkaido Yo series.
The taste was interesting, there was a strong sweet purple potato essence taste and it was also slightly sour as well because of the yogurt.
I really liked it because sweet purple potato is always sweet and this time it was made into froyo so it tasted difference with the sourness.
Other flavours I have tried in the Hokkaido-Yo series:
Circle K Hokkaido-Yo Peach flavour
Circle K Hokkaido-Yo Original, Grape and Fuji apple flavours
