Miso paste is becoming increasingly easy to find and can be considered a staple item in regular supermarkets. They are usually found in the Asian section of the supermarket, and for those who have a specific Japanese section, you’ll find them there. They are usually in a soft packet, a rectangular plastic tub like margarine or a cylindrical jar like a jam. There are a few types of miso paste, so be sure to look out for labels that say shiro miso, white miso or soybean paste, white.
