This product is a summer-only country ma'am that "freezes and eats". By freezing, the texture of the cookie changes and the chocolate chips feel crispy. It seems that the way to eat frozen was a standard in some areas.
There are two flavors, "chocolate ice cream" with almonds added as an accent to chocolate-flavored cookies, and "Ujikintoki" with the popular flavor of shaved ice as a motif. Mini chocolate chips are used for both so that you can easily feel the texture when frozen.
