While I didn't get the full Sasebo Burger experience, I can only hope that it's not close to this food drop. Definitely more of a novelty than a form of sustenance, you're really trading taste for calories in this treat. Food science has come a long way, though, and there's a disturbing accuracy to these that, for a hard candy, actually had a powerfully smoky and somewhat meaty flavor. Where it was really lost was in the remaining aspects. Any creamy cheese or mayonnaise flavors ended up tasting overly sweet and indistinguishable, lending us the descriptor of "smoked butterscotch." Don't quote us on it. It's not an unpalatable flavor, but it's really something strange. At first, I thought this was coming from the sugared coating on the candies, but it lingered to the point of being intentional.
I don't know whether the burger buns in Japan are sweeter; perhaps someone can clarify on that for me, but I do know that some acidity in this- an element of mustard or pickles, would have cut the sweetness immensely and possibly tasted better. I'm confident that they can do it. After all, if they can manufacture sweet meat, anything is possible, right? Buy this for the novelty. It's neither satisfying to a savory or sweet tooth, but still delights.
