This is a dried rose. It tastes like dried stawberries. It’s very sweet, and the petals are small and make it have a different texture from strawberry. Apparently all that is done is some sugar or honey is added for sweetness. I think it was my first time eating a rose and I have to admit they don’t just smell good.
Update
It turns out the translator was wrong and this is actually hibiscus, which makes more sense.
