tablespoons light soy sauce or shoyu
tablespoons rice vinegar or black vinegar
tablespoons warm water
scallion, trimmed and thinly sliced
tablespoon granulated sugar
teaspoon toasted sesame oil
- Prepare the dipping sauce: In a small bowl, stir together all ingredients until the sugar dissolves. Set aside, or prepare in advance and store in a sealed container in the refrigerator for up to several weeks.
- Prepare the pancakes: In a large bowl, combine sauerkraut and sauerkraut juice. (If you don’t have enough sauerkraut juice, you can make up the difference with cold water.) Add onion, scallions, flour, starch, sugar, pickled peppers and the cold water. Stir rapidly with a spoon just until no dry flour remains. (Do not overmix the batter.) The batter should be thin enough to flow around when you tilt the bowl.
- Heat 2 tablespoons oil in the bottom of a flat-bottomed wok or an 8- to 10-inch nonstick skillet over medium-high until shimmering. You should be able to make about two 10-inch pancakes or three 8-inch pancakes, or several smaller pancakes. Add enough batter that you can spread it into a thin pancake with the back of a spoon. Let the pancake cook, undisturbed, until the bottom of the pancake is set, about 2 minutes. Use a thin spatula to gently release the pancake from the pan if it is sticking at all. Continue to cook, swirling pancake around to encourage even browning until the first side is well browned with a few darker spots, another 2 to 3 minutes.
- Use a wide spatula to carefully flip the pancake. Continue cooking until second side is well browned, about 4 minutes.
- Slide the pancake out onto a cutting board, and cook remaining pancake batter, repeating Steps 3 and 4. Once cooked, cut into wedges with a pizza slicer or knife and serve with the prepared dipping sauce.
