The jam doesn't really seem like a separate flavor to me at all—but it might add a hint of extra creaminess to the center of the mochi even when it's frozen solid. Otherwise, these are almost exactly like the Mango Mikawaya Mochi that Trader Joe's has carried for years. Now I'm not going to say this stuff is Mikawaya brand, because I couldn't tell you if that's the case for sure, but I will say that it's extremely similar in taste and texture. Actually, now that I think about it, Mikawaya is based in California and this product is imported from Thailand, according to the box. So...probably not Mikawaya.
This product has a great mango-esque flavor, but it is particularly sweet—which is totally fine by me, but then again, I do have a sweet tooth. Mochi and mango are generally a pretty good combo...well, okay, there was this one instance where they were a little goofy together. I'd probably still choose vanilla or strawberry flavor first, but by and large, mango and mochi are friends.
Mochi and mushroom, however...
Four stars from me. Sonia will go with three and a half.
Bottom line: 7.5 out of 10.
