The Roles of Shoyu, Mirin, and Dashi"},"content":{"rendered":"

The main ingredients of Japanese sukiyaki-style black soup are shoyu (Japanese soy sauce), mirin, and sugar, which give it a dark color and a sweet-salty taste. Many recipes add sake and dashi or kombu to enhance the aroma and umami, then dilute with water or stock to a suitable strength for cooking ingredients.<\/p>\n\n\n

How Is Black Soup Related to Sukiyaki Sauce?<\/h2>\n\n\n\n

The black soup at Thai shabu restaurants takes its flavor direction from “warishita,” the seasoning sauce for Japanese sukiyaki, but it is diluted to make enough to cook ingredients throughout the meal. Read the full background inthe origins of black soup<\/a><\/p>\n\n\n\n

What Does Each Ingredient in Black Soup Do?<\/h2>\n\n\n\n

1. Shoyu provides saltiness and dark color<\/h3>\n\n\n\n

Shoyu is the main ingredient that gives the broth its saltiness, aroma, and color. How dark the color is depends on the type and amount of shoyu, but a dark color doesn't mean the broth has to be very salty, because the sweetness from mirin and sugar helps balance the taste.<\/p>\n\n\n\n

2. Mirin provides mild sweetness and a Japanese aroma<\/h3>\n\n\n\n

Mirin is a Japanese seasoning that gives sweetness and a distinctive aroma, and it is often paired with shoyu in sukiyaki sauce. Each type of mirin has a different level of sweetness, and “mirin-flavored” products may be sweeter or smell different from what the recipe intends, so taste before adding more sugar.<\/p>\n\n\n\n

3. Sugar balances sweet and salty<\/h3>\n\n\n\n

Sugar cuts the saltiness of the shoyu and rounds out the flavor. The amount should be considered together with the sweetness of the mirin. If the recipe already uses sweet mirin, reduce the sugar and add it a little at a time, because as the broth simmers and water evaporates, the sweetness becomes stronger.<\/p>\n\n\n\n

4. Cooking sake enhances aroma and depth of flavor<\/h3>\n\n\n\n

Sake appears in many warishita recipes and helps enhance aroma and roundness, but it isn't necessary in every black soup recipe. Some sake and mirin contain alcohol; if you want to avoid it, choose a recipe without sake and check the ingredients of the mirin you use.<\/p>\n\n\n\n

5. Dashi or kombu adds umami<\/h3>\n\n\n\n

Dashi is Japanese stock, which can be made from kombu, dried bonito, or mushrooms depending on the recipe. Kombu is soaked or gently simmered to give a milder umami. If you don't want fish ingredients, use kombu or mushroom dashi instead of dried bonito.<\/p>\n\n\n\n

6. Water or stock sets the strength<\/h3>\n\n\n\n

Water or stock is used to dilute the seasoning base to suit shabu cooking. If you use a concentrated sauce without diluting it, the taste will be too strong, and as meat, vegetables, and mushrooms go into the pot, the flavor of the broth will also change during the meal.<\/p>\n\n\n\n

Which Ingredients Are Essential and Which Are Optional?<\/h2>\n\n\n\n

Black soup can't do without shoyu, mirin (or sugar), and water, while sake, dashi, and kombu are optional additions that each recipe includes differently.<\/p>\n\n\n\n

How Do You Balance the Flavor of Black Soup?<\/h2>\n\n\n\n

Balance the flavor of black soup by adding shoyu, mirin, and sugar to water or stock a little at a time, and taste while the broth is hot, because it tastes different hot than cold. If using sake, add it as the recipe specifies.<\/p>\n\n\n\n
