Miso-Lemon-Soy Sauce

A simple, glossy Japanese sauce with a salty-tangy profile, built around miso, soy sauce, and lemon. Serve it in small amounts to coat tofu, steamed vegetables, grilled fish, or hot rice.

Ingredients

  • 80 g Japanese white miso
  • 45 ml naturally fermented Japanese soy sauce
  • 45 ml fresh yellow lemon juice
  • 30 ml Japanese mirin
  • 15 ml Japanese rice vinegar
  • 12 g fine blond sugar
  • 2 tsp toasted sesame oil
  • 30 ml hot water
  • 8 g fresh ginger

Method

  1. Juice the lemon and strain the juice to remove the seeds and thick pulp; the sauce should remain smooth and glossy.
  2. Peel the ginger and grate it very finely. Squeeze the grated pulp between your fingers or in a small strainer to collect mostly the fragrant juice and avoid a fibrous texture.
  3. Put the white miso in a heatproof bowl. Gradually add the soy sauce, whisking from the center: the miso should loosen into a supple paste before becoming fluid.
  4. Add the mirin, rice vinegar, sugar, and ginger juice. Whisk until the sugar no longer crunches under the whisk and the surface becomes satin-like.
  5. Gradually pour in the hot water, whisking constantly. The heat should be sufficient to loosen the miso, but the sauce must never boil; it should coat the back of a spoon in a thin, even layer.
  6. Add the lemon juice last to preserve its fresh aroma. Taste: the sauce should be umami-rich and salty first, then lively, with clear but non-aggressive acidity.
  7. Drizzle in the toasted sesame oil, whisking until it is barely floating on the surface. The sauce should be homogeneous, glossy, and slightly thick.
  8. Let the sauce rest at room temperature for a few minutes before serving, so the miso can hydrate fully and the flavors can meld. Whisk again just before coating.
