Gamja jorim, or salty-sweet soy-simmered potatoes, is a common banchan (small plate) on the Korean table. For our version, we added gochujang (Korean fermented chili paste) for a little heat and extra umami. Yukon Gold potatoes 1½ to 2 inches in diameter worked best, but creamier potatoes were good, too. If your potatoes are very small (about 1 inch in diameter), cut them in half; if larger than 2 inches, cut them into eighths. Depending on the sugar content of your potatoes, they may or may not brown lightly as they cook before the soy mixture is added. This is a great side dish to grilled meats and seafood.
