When I saw this box on display at a Korean market, the English sign in front of it said, "Black Sandwich Cracker". This intrigued me because what is pictured on the box resembles a knock-off of an Oreo cookie, not a cracker. I wanted to know if the contents of the box actually were cracker-like confections and it only cost me 50 cents to find out.
When I got home and started looking more carefully, I saw that these are made by Japanese snack-making power house, Lotte. In fact, if you peruse the Korean web site, you'll see that there is substantial product overlap between countries including Ghana chocolate bars. I think that products produced for both countries are essentially identical. However, I could not find a chocolate sandwich cookie (or cracker) option on Lotte's Japan site. Perhaps they threw in the towel in that market and gave in to Oreo.
The main benefit of these cookies for me over Oreos are that they are sold more cheaply and in a smaller package. The first time my husband and I bought a standard size package of Oreos after returning to America, it took four months to eat it all. The second time, it took longer and we had to throw the rest away. It's just too much cookie for a couple of people who aren't gobbling them down like a crazed 8-year-old.
Of course, a 50-cent box is unlikely to live up to the greatness of Oreo, right? Well, maybe... The truth is that these were very good cookies. The bitter chocolate cookie exterior was flavorful and had a good texture. It lacked some of the fatty, crumbly nature of an Oreo, but it did not go anywhere near "cracker" territory. It was a more than serviceable cookie with just enough cream to make it interesting without making it too sweet or cloying.
Frankly, for my tastes, these were better than a standard Oreo, but I'm guessing those who are into double-, triple-, and whatever multiple numbers of "stuffs" they enjoy in Oreos will find the filling amount paltry and insufficient. It truly depends on how sweet you like your cookies. Oddly, the calorie count is not enormously lower despite the lesser sweetness and white stuff. The cookies are 45 calories each, but are smaller than an Oreo.
I wouldn't say that one should bust a gut scrambling down to the local Korean market (I got these at a place called "Super Kyo-Po Plaza"), but I'm guessing you could get them at any Korean market... provided you have access to one. I certainly would buy them again if I wanted to have an "Oreo" cookie around. They're not "better", but they are different in a way that suits my tastes (and pocketbook) better.
