This is a cracker that every cracker fan should try out at least once in their life. You can get an idea what type of food this is, solely by the name - after all, it is called "wasp crackers." It is consumed like any other cracker with a cup of warm milk (or maybe with a smoothie) and it makes for the perfect breakfast. It is a good alternative if you're tired from the good old chocolate chip cracker.
It is supposed to be very popular in Japan and if you can get over the fact that there are wasps in it, it shouldn't taste much different from a regular cracker. And as in other foods with an insect in them, it probably has some health benefits, things like curing cancer and such, and it has a lot of protein.
