- 3/4 pound Napa cabbage, cut crosswise into 1/3-inch-wide strips
- 3 tablespoons finely chopped carrot
- 1 1/2 teaspoons coarse salt
- 1 ounce (30 grams) kombu, about 20 square inches
- 4 fresh green shiso leaves or 1/4 cup fresh basil, chopped
- Toss together cabbage, carrot, and salt in a bowl. Put kombu in a narrow straight-sided container (5 to 6 inches in diameter) and top with cabbage mixture. Cut a piece of cardboard to fit just inside container and enclose it in a sealable plastic bag. Top cabbage with plastic-covered round and stack 4 to 6 pounds of canned goods on top to weight it. Chill weighted cabbage at least 3 hours.
- Discard kombu. Squeeze excess liquid from cabbage and toss with shiso.
