Korean Kohlrabi Fresh Salad (Saengchae)

Though it resembles mu-saengchae made with radish, the two diverge clearly in texture and flavor. Kohlrabi is a brassica, but instead of leaves or roots, the rounded swollen stem base is the edible part. Its exterior is firm and waxy, while the flesh inside is juicy, light, and gently sweet in a way that resembles a crisp pear rather than the earthy sharpness of radish. The thick outer rind must be generously peeled to strip away the fibrous layer just beneath the skin, and the kohlrabi is then cut into matchstick strips about 4 to 5 centimeters long and a few millimeters wide. Cutting too thin causes the strips to wilt quickly as they draw moisture under the dressing. Fish sauce contributes marine umami to kohlrabi's quiet sweetness, while vinegar slows moisture loss and extends the window of crispness after seasoning. Gochugaru adds heat and the brick-red color associated with most saengchae. Served beside grilled fatty meats, the tangy, crunchy salad functions as a palate cleanser between bites. Kohlrabi is at its sweetest and most firm during peak seasons in spring and fall, which is when this banchan appears most frequently at Korean tables.
