kikkoman products used:


3/4 cup Kikkoman Soy Sauce
1/4 cup canola oil, plus extra for searing tuna
2 tablespoons sugar
1 tablespoon orange juice
2 teaspoons grated ginger
1 teaspoon minced garlic
1 teaspoon chili flakes
1 pound ahi tuna, cut into a 2- by 6-inch block
4 thick slices grilled or toasted sourdough bread
cilantro leaves

Edamame Puree:
3 cups shelled edamame (fresh soybeans)
1 1/2 cups extra virgin olive oil
3 tablespoons finely chopped parsley
3 tablespoons finely chopped mint
3 tablespoons finely chopped cilantro
1 to 2 tablespoons sambal (chili paste), or to taste
1 tablespoon plus 1 teaspoon lemon juice, divided
1 teaspoon red wine vinegar
1 teaspoon minced garlic, divided
1 1/2 teaspoons kosher salt, divided


Whisk together soy sauce, 1/4 cup canola oil, sugar, orange juice, ginger, garlic and chili flakes. Place tuna in marinade; turn to coat. Refrigerate 4 hours, turning occasionally. Remove tuna from marinade; pat dry with paper towels. In cast iron or heavy-duty skillet, heat canola oil over high heat. Sear tuna about 30 seconds on each side. Refrigerate until cool.

Spread 1 heaping spoonful Edamame Puree (recipe below) onto each slice of bread. Slice tuna into 1/4-inch-thick slices. Layer tuna over puree; spoon whole edamame over tuna. Garnish with cilantro leaves.

To make Edamame Puree: Combine edamame and olive oil in saucepan over medium high heat; cook 5 minutes. Drain, reserving edamame and oil separately. In large bowl, stir together parsley, mint, cilantro, sambal, 1 teaspoon lemon juice, vinegar, 1/2 teaspoon garlic, 1/2 teaspoon salt and 6 tablespoons reserved olive oil. Add 1 cup reserved edamame; stir to combine. Set aside.

In food processor, process remaining edamame to make a chunky puree. Stir in 1/2 cup reserved olive oil, 1 tablespoon lemon juice, 1 teaspoon kosher salt and 1/2 teaspoon garlic.

Even people who love soy sauce and use it all the time are often surprised to learn what it is and how it’s made. We make ours from just four simple ingredients—water, soybeans, wheat, and salt. Those ingredients are transformed through a traditional brewing process—much like making wine or beer—that has remained unchanged for centuries.
