3 tablespoons toasted sesame seeds

2 teaspoons sugar

1 tablespoon plus 1 teaspoon soy sauce

1 tablespoon sake

1 tablespoon water (more to taste)

1/2 teaspoon dark sesame oil

 

Bring a large pot of generously salted water to a boil. Fill a bowl with ice water. Blanch the spinach for 10 to 20 seconds in the boiling water and transfer to the ice water using a deep-fry skimmer. Drain and gently squeeze out water. Chop coarsely. Make the dressing. If your sesame seeds have not been toasted, heat a dry skillet over medium heat and add the sesame seeds. Stir and shake the pan constantly, and as soon as the seeds turn golden and smell nutty, transfer to a  mortar and pestle or to a spice mill. Allow to cool. Grind the seeds just until crushed.  Combine the soy sauce and sugar in a small bowl and stir until the sugar has dissolved. Add the sake and water, then stir in the ground sesame seeds. Thin out with water. Toss with the spinach and stir together until the dressing infuses the spinach. Be careful not to bruise the spinach leaves. Divide into four small bunches and place in the middle of four small plates or bowls. Drizzle on a few drops of sesame oil. Serve at room temperature.
