I start by chopping the cabbage finely and sprinkling it lightly with salt. Then I let it sit for about 10 minutes so the salt can pull out extra moisture. This step matters more than people think, because skipping it leads to watery, soggy dumplings later.
Once the cabbage has rested, I squeeze out as much liquid as I can using a clean towel. Then I toss it into a bowl with garlic, ginger, green onions, soy sauce, and sesame oil. I mix everything until it's evenly coated and smells fragrant.
I lay a wrapper flat on my cutting board and spoon about a tablespoon of filling into the center. I wet the edges lightly with water, then fold and pleat or simply press the sides together. A tight seal is the whole game here.
I heat oil in my skillet over medium-high heat, then place the dumplings flat-side down in a single layer. I let them sit untouched for 2 to 3 minutes so the bottoms develop that deep golden crust.
Once the bottoms are browned, I carefully pour in a few tablespoons of water and cover the pan immediately. I let them steam for 4 to 5 minutes so the filling cooks fully inside the wrapper.
I remove the lid and let any leftover water cook off for another minute or two. This brings back the crispy bottom one last time before I plate them up hot with sauce on the side.
