What Is Unagi Sauce?

Unagi sauce, also known as eel sauce, is a thick, sweet, and savory sauce that is a staple condiment in Japanese cuisine. It has a glossy, dark brown appearance and a rich umami flavor profile.

Unagi sauce is most commonly associated with unagi, or freshwater eel, which is grilled and then glazed with the sauce. However, it can also be used with many other ingredients like fish, chicken, pork, vegetables and more.

The main ingredients in unagi sauce are soy sauce, mirin, sake, and sugar. Additional ingredients may include dashi, ginger, and MSG. The soy sauce provides saltiness, the mirin adds sweetness, and the sake contributes further umami savoriness.

How is Unagi Sauce Made?

Making unagi sauce is relatively simple, requiring just a few pantry staples. Here is a basic recipe:

  • Soy sauce
  • Mirin (sweet Japanese rice wine)
  • Sake (rice wine)
  • Sugar
  • Optional: dashi stock, grated ginger, MSG

The ingredients are combined together in a saucepan and simmered over medium heat. The soy sauce, mirin, and sake provide the classic Japanese umami flavors. The sugar balances out the saltiness and enhances the glaze-like texture. Ginger can be grated in for extra punch.

As the sauce simmers, the liquid will reduce down into a thick, glossy consistency that coats and clings to foods beautifully. Once it reaches the desired thickness, the unagi sauce is ready to use.

What Does Unagi Sauce Taste Like?

The hallmark taste of unagi sauce is its enticing blend of sweet and savory. The soy sauce base provides a rich, salty umami foundation. The mirin introduces a touch of sweetness to contrast the salt. Sake adds a subtle fermented flavor.

Overall, the sauce strikes a delicate balance between savory and sweet. It has a smooth, thick texture and a dark caramel color. The flavor is complex, yet harmonious – sweet upfront, followed by a pleasant savory kick. It’s a very moreish condiment!
