What to buy: Tobanjan is a spicy, fermented soybean-chile paste common in Japanese and Chinese cooking. It is sometimes labeled “Chili Bean Sauce” and is available at most Asian grocery stores and online.
Miso is a Japanese culinary staple made by fermenting rice, barley, or most commonly soy. The two main types are white (or shiro) miso, which has a sweet, mild flavor, and red (or aka) miso, which is aged and has a salty, umami flavor. You can find miso paste refrigerated at most grocery stores.
