Author Notes

This sauce is borrowed from Roy's restaurant's signature Blackened Ahi with Soy Mustard Sauce and Beurre Blanc, but this sauce is too easy and too good not to parade through all sorts of other foods: brown rice, edamame, fish of all kinds, and, notably, steak. Adapted slightly from Genius Recipes

Roy Yamaguchi's Soy-Mustard Sauce (a.k.a. 3-Ingredient Steak Sauce)
  • Prep time 1 hour
  • Cook time 10 minutes
  • Makes 3/4 cup
Ingredients
  • 1/4 cup mustard powder, preferably Colman’s
  • 2 tablespoons hot water
  • 2 tablespoons rice wine vinegar
  • 1/4 cup soy sauce
In This Recipe
Directions
  1. Mix the mustard powder and hot water together in a cup to form a paste. Let sit for a few minutes to allow the flavor and heat to develop.
  2. Add the vinegar and soy sauce, mix together, and pass through a fine-mesh sieve into a bowl. Yamaguchi recommends covering and refrigerating for at least 1 hour to allow the flavors to develop, but the sauce will still taste delicious right away if you're in a hurry. Serve with steak, or anything else you like (see headnote above for ideas).

Genius recipes surprise us and make us rethink cooking tropes. They're handed down by luminaries of the food world and become their legacy. They get us talking and change the way we cook. And, once we've folded them into our repertoires, they make us feel pretty genius too.
