Green Tea Sauce for Fish

(enough for two main-course portions of fish)

Ingredients:

• 1/3 cup brewed dark green tea, hot
• 3 tablespoons unsalted butter
• 1/4 teaspoon powdered dashi (Katsuo Dashi No Moto made by Shirakiku is one brand)
• a few drops dark sesame oil

Directions:

1. Place the brewed green tea in a saucepan with sloping sides over medium-high heat. Add the butter all at once, and begin swirling with a whisk. Within a minute or so, the butter should melt, and the green tea sauce should be silky.
2. Swirl in dashi powder, and taste for seasoning.
3. Finish with a few drops of sesame oil, swirling them in. Serve immediately.
