Saba Miso Soup is a comforting and nourishing dish that combines the umami flavors of mackerel with the richness of miso. To make this soup, you will need Saba fillets, miso paste, dashi stock, tofu, green onions, and seaweed. Start by preparing the dashi stock by combining water and dried kelp in a pot and bringing it to a simmer. Remove the kelp and add bonito flakes to the pot, simmering for a few more minutes. Strain the stock to remove any solids. In a separate pot, bring the dashi stock to a boil and add cubed tofu and sliced Saba fillets. Cook for a few minutes until the fish is cooked through. Reduce the heat and dissolve miso paste in a small amount of the hot broth, then add it back to the pot. Stir gently to combine. Serve the Saba Miso Soup hot, garnished with chopped green onions and a sprinkle of seaweed. This hearty and flavorful soup is perfect for cold winter days or when you need a comforting meal.
