Azuki Bar is a popular frozen popsicle in Japan made from sweet Azuki red bean paste. This cool treat has been enjoyed for its nutty flavor and grainy bean texture for decades. Azuki Bar contains nothing complicated or artificial, but it’s pleasantly sweet and full of flavor. It looks just like any popsicle with a stick. It’s a wonderful cold dessert during Japan’s brutally hot and humid summers, but it also can be eaten all year round.
