Spinach Dumplings With Tofu and Rice Noodles

Wash the spinach well. Drain and pat dry. Add the spinach, salt, and 1 cup (240 ml) water to a blender or food processor and blend until it forms a smooth puree. Strain the mixture through a cheesecloth, reserving the liquid in a measuring cup, which should yield at least 1½ cups (360 ml). Put aside the drained spinach for the filling.

In a large bowl, add the flour and gradually stream in 1 cup (240 ml) of the reserved spinach liquid, using one hand to mix.

Then gradually add the remaining spinach liquid a little at a time, using both hands to knead for about 5 minutes, until it all comes together and forms a smooth dough. You may not use all the liquid. Cover the dough with plastic wrap and let rest at room temperature for 10 minutes.

After resting, remove the plastic wrap and knead the dough in the bowl a few more times. Cover again with plastic wrap and let rest for another 10 minutes. You may repeat this process one more time for a chewier dough, but the chewier the dough is, the stickier and trickier it will be to work with.

Cover with a damp cloth or plastic wrap while you prep your fillings.

Do Ahead: The dumpling skins are best used day of, but if you can’t make the dumplings right away, it’s best to store the dough in unrolled pieces, generously dusted on all sides with flour to prevent sticking. Cover with plastic or place in a covered container and store for up to 2 days in the refrigerator.

Prep a bowl of ice water. Bring a medium pot of water to a boil over medium heat and add the carrot. Cook for about 5 minutes, then immediately remove the carrot to the bowl of ice water to shock them and stop the cooking process. Meanwhile, marinate the green onion in the sesame oil for 5 minutes.

Add the bok choy to the boiling water and cook for about 1 minute, then remove and add to the ice water. Once cooled, squeeze the bok choy between your hands or in a dishcloth to drain it of all water.

Finely chop the carrot and bok choy, then add them to a bowl and combine with the reserved spinach.

Add the vermicelli noodles, fried tofu, ginger, green onion in sesame oil, salt, and white pepper powder to the bowl of vegetables and mix to combine by stirring in one direction to promote better cohesion of the filling.

Set a small pan over low heat and add the vegetable oil. Add the Sichuan peppercorns and fry until fragrant, about 8 minutes. Carefully strain and discard the peppercorns and pour the infused oil into the bowl of dumpling filling. Stir to combine.

Allow the filling to cool slightly, then crack in the egg and mix in one direction to combine.

Do Ahead: Store in an airtight container in the fridge until ready to use, up to 3 days, or freeze for up to 3 months.

Using your hands, roll the dough into a long and even snake-like cylindrical shape until it is about 1 inch (2.5 cm) in diameter.

On a large wooden board or a clean work counter, use a knife to cut even, 1-inch (2.5-cm) segments of the dough. (Note: You can also rip pieces off by hand, but it requires a certain experience, accuracy, and speed. Cutting with a knife is definitely easier.)

Sprinkle a little flour on the board or work surface to prevent sticking (but don’t go overboard). Place each segment on the board with the cut part facing up (like a little stubby piece of firewood), and use the heel of your palm to flatten it slightly on the board.

Hold a small cylindrical roller with your dominant hand. With your other hand, hold the piece of dough by the edge. From the opposite edge, gently roll the piece of dough with your roller toward the center and then back, then turn the dough slightly and roll again toward the center and back. Repeat this several times until the dough becomes an almost-perfect circle, 2½ to 3 inches (6 to 7.5 cm) in diameter. The idea is to roll the dough out evenly from the sides so it is smooth and round, with the center slightly thicker than the edges (around 1⁄8 inch/3 mm thick overall).

Repeat this process for all pieces of dough and use immediately in folding dumplings.

Prep a tray or a plate by sprinkling flour on the bottom to prevent sticking.

Put a dumpling skin on the palm of your hand.

Use a spoon (or chopsticks) to scoop 1 to 2 tablespoons of your filling mixture into the middle of the skin. Fold the skin in half so the two sides meet and can be pressed into each other to bind. Squeeze the rest of the sides together as well. Make sure the sides are pressed fully into each other to avoid the dumplings breaking, and avoid any filling touching the edges, as the oil in the filling could prevent the sides from sticking properly. (Note: If you’re using store-bought skins, wet the rim of the wrapper with a little bit of water to help the edges seal. The goal is to maximize the amount of filling in your dumpling, but not put so much that the dumpling breaks or cannot be pressed together.)

Place the finished dumplings in your prepared tray or plate, being careful to space them apart so they don’t stick.

Do Ahead: These are best cooked and eaten fresh, but you can also place the entire tray of folded dumplings in the freezer, covered carefully with plastic wrap. Once the dumplings are frozen solid, transfer them to an airtight zip-top bag and freeze for up to 3 months.

Bring a large pot of water to a simmer, with the water on the verge of boiling. Right before the water boils, gently add the dumplings—this timing is crucial to prevent cracking. Keep the dumplings moving so they don’t stick. When the water comes up to a boil again, add ½ cup (120 ml) cold water and stir. Repeat two more times. Once it comes up to a boil the fourth time, the dumplings should be floating and ready to eat, but if you’re nervous, go ahead and cut one open to check. The entire process should take 10 minutes. Fish out the dumplings with a slotted spoon and serve with dumpling sauce, chili oil, sesame oil, and roasted sesame seeds.
