When it comes to salads, I'm much more interested those made with vegetables, fruit, nuts and other ingredients than anything with lettuce or other leafy greens – creations like the Tosa sea salad in Washoku, Elizabeth Andoh's splendid book about Japanese home cooking. (An exciting aside: Elizabeth Andoh has a new book scheduled for release in October: Kansha: Celebrating Japan's Vegan and Vegetarian Traditions.)It has three main ingredients – cucumber, wakame and radish sprouts – and a delicious slightly smoky dressing. The slight sweetness of the cucumber, the mellow oceanic nature of the wakame, and the sharp bite of the sprouts are an unlikely trio that goes great together and meshes with the smoky vinaigrette. The vinaigrette is where I make a major diversion from Andoh's recipe. In her recipe, the smoke flavor comes from katsuo-bushi (dried bonito flakes), a specialty of the recipe's namesake, the region of Tosa on Shikoku Island (not the dog; see map at the bottom of the post). To bring smoke into the dressing while keeping it vegetarian, I use lapsang souchong tea, a Chinese variety that has been dried over burning pinewood fires, thus imparting it with a smoky essence (so much so that I wonder how anyone could drink it straight.).
Before we get to the recipe, a side note about wakame (Undaria pinnatifida): this variety of kelp is native to Asia, but is an aggressive invader, earning a place on the IUCN's list of the 100 worst invasive species. In recent decades, it has become established in Europe, New Zealand, Australia and Southern California. Just last year, it was spotted in San Francisco Bay for the first time, a worrisome new development for an already highly damaged ecosystem, as an article in the San Francisco Chronicle reports. Even if we all regularly ate the Tosa sea salad we'd probably barely make a dent in the invader's population.
Tosa Sea Salad
Adapted from Washoku by Elizabeth Andoh
(Unit conversion page)
4 Japanese or other cucumbers with edible peel, about 3 ounces each
1 t. coarse salt
2 T. dried wakame (see note 1)
2 ounces radish sprouts, rinsed, trimmed and cut into 1/4-inch length (see note 2)
1/4 cup smoky vinaigrette (recipe below)
Cut the cucumbers in half lengthwise, then slice thinly on a diagonal to make half-ellipses. Transfer to a bowl, sprinkle with the salt, and toss. Allow to rest for 10 minutes. Rinse, drain and squeeze gently to remove any excess liquid.
Cover the wakame with cool water, soak for 5 minutes, and then drain, rinse and drain again. If necessary, chop the rehydrated wakame into bite-size pieces. Combine with the cucumbers.
Just before serving, divide the cucumber-wakame mixture into 4 portions, top with the radish sprouts and pour some vinaigrette over each portion.

1/4 cup brown rice vinegar (or plain rice vinegar)
1 T. sugar
1/4 t. salt
1 piece kombu, 2 inches square
1 t. lapsang souchong tea (see note 3)
Optional: To remove some of the caffeine from the tea without losing too much smoke flavor, pre-steep the tea by pouring a cup of boiling water over the leaves, letting it steep for 3 or 4 minutes, then draining. (for details about caffeine in tea, see my two posts on the subject.)
Combine the vinegar, sugar, salt, and kombu in a small non-reactive saucepan. Bring to a simmer over low heat, stirring occasionally to dissolve the sugar and salt. When the liquid has reached a simmer, add the lapsang souchong tea (pre-steeped or not), stir and turn off the heat. Allow to cool in the pan. Pour through a fine strainer to remove the solids.
Add a dash of soy sauce if the dressing is too sweet, a dash of mirin if it is too salty.
Notes:1. Wakame can be found in stores that specialize in Asian products, especially those with a Japanese or Korean tilt. It usually comes in small plastic bags that don't seem to hold much, but as the picture above illustrates, the plant expand a lot when it rehydrates.
2. Radish sprouts are grown from daikon or radish seeds. Since they are sold by a sprout specialist at my local farmers market, I haven't looked for them elsewhere, but would guess that you could find them in natural food stores or Japanese groceries.
3. Lapsang souchong, a tea that has been dried over burning pinewood fires, is used to impart a smoky flavor to the viniagrette. Andoh's original recipe calls for 1/3 cup loosely packed katsuo-bushi, a variety of dried bonito that has a smoky flavor. The fish flakes are sprinkled over the simmering liquid and heated for 30 seconds before turning off the heat.
