Ingredient guide
Korean soy sauce (ganjang) is the salty, savory base of marinades, soups and dipping sauces. Two kinds matter: all-purpose soy sauce (jin-ganjang), which is what most recipes mean, and a thinner, darker, much saltier soup soy sauce (guk-ganjang) used to season soups.
Salty and deeply savory with a little sweetness. The soup type is saltier and lighter in color.
For everyday cooking, a bottle labeled Korean soy sauce (진간장) or any naturally brewed soy sauce. Japanese shoyu is the most widely sold stand-in and works well.
Keep it in a cool cupboard. Refrigerating after opening keeps the flavor for many months.
Works in any country — look for these names, in these kinds of shops.
