Ingredients

Sunomono

  • 2 Japanese cucumbers or 3 Persian, or 1 English (10 to 12 ounces total)
  • ½ teaspoon kosher salt
  • 2 tablespoons dried cut wakame optional but recommended

Dressing (Amazu)

  • 4 tablespoons unseasoned rice vinegar
  • tablespoons sugar
  • ½ teaspoon kosher salt
  • 1 teaspoon soy sauce

Garnish

  • 1 teaspoon toasted sesame seeds
  • Grated fresh ginger optional

Instructions

  • Combine the vinegar, sugar, salt, and soy sauce in a small saucepan. Warm over medium heat, stirring, just until the sugar dissolves, about 1 to 2 minutes. Do not boil. Microwave option: combine in a microwave safe bowl and heat 20 to 30 seconds, then stir until the sugar dissolves.
  • Cool the dressing completely. Warm dressing wilts the cucumbers and you lose the crunch factor. Refrigerate it while you prep everything else.
  • Rehydrate the wakame (if using). Cover with cool water and soak 5 to 10 minutes. It expands about tenfold. Drain and squeeze dry.
  • Slice the cucumbers paper thin, about 1/16 inch. A mandoline is very helpful. Toss with the ½ teaspoon salt and let sit 10 minutes.
  • Squeeze the cucumbers firmly in your hands to drain excess liquid. Rinse under cold water, squeeze again, then pat dry. Important for crunchy versus soft bites.
  • Combine the cucumbers and wakame in a bowl and toss with the cooled dressing. Chill 15 to 20 minutes.
  • Top with sesame seeds and a small mound of grated ginger. Serve with a slotted spoon to let excess dressing drip back and not onto your plate.

Notes

Crumble the wakame in your fingers a bit before rehydrating. This gets you smaller pieces rather than long ribbons of seaweed, for a more even bite.
Heat Factor: Mild. There is no heat in the base recipe. For a spicy touch, sprinkle chili flakes over the top, or drizzle with chili crisp or rayu (Japanese chili oil). Shichimi togarashi or a bit of yuzu kosho whisked into the dressing both work great.
Seafood Variations: Add 4 ounces shredded imitation crab (kani), 4 ounces thinly sliced cooked octopus (tako), or 4 to 6 ounces halved cooked shrimp (ebi) after dressing.
Storage: Best the day you make it. Keeps in a sealed container in the refrigerator up to 2 days, though the cucumbers soften as they sit.
