In a mixing bowl, gradually stir the water into the flour.
100 g wheat flour, 50 ml hot water
Add the egg yolk and knead until a smooth dough forms.
1 egg yolk
Let rest, covered, for 30 minutes.
Divide into pieces of about 5g.
Roll into balls, flatten them, and roll out to make discs about 7.5cm. Dust well with cornstarch to keep them from sticking to one another.
cornstarch
While you form the remaining discs, cover with a damp towel.
Ingredient Preparation
Rehydrate the mushrooms in hot water for 10–15 minutes. Squeeze out as much water as possible, then finely mince.
4 dried shiitake mushrooms (pieces)
Slice the pork into strips, then mince. Soak in water and massage for 1–2 minutes. Let sit for 10–15 minutes. Drain in a colander and squeeze out as much water as possible by pressing firmly. Tip: bundle everything in a towel to make it easier.
227 g pork, 2 tablespoons water
Wrap the shrimp in a paper towel and press to remove as much moisture as possible. Mince into small pieces.
113 g shrimp
Slice the carrots, cut into strips, then into very fine pieces.
15 g carrot
The Famous Marinade
In a bowl, combine the pork with the marinade ingredients and mix well for 2–3 minutes. Let rest for 15 minutes.
Add the mushrooms and shrimp. Mix well for a few minutes, cover, and refrigerate for 4–8 hours. Yes, really.
The Folding From Hell
Lay a wrapper flat in your palm.
20 siu mai wrappers
Spoon about 1 teaspoon of filling onto the wrapper and gently flatten it.
Make a circle by pressing your index finger and thumb together, and place the wrapper on the circle. Shape your other fingers into a funnel.
Using the handle end of a spoon, push down into the center of the wrapper, into the hole made by your fingers.
Compress the filling in the wrapper by pressing with your spoon while supporting the sides with your fingers. Rotate the dumpling several times.
Squeeze the bottom half of the dumpling to push some of the filling upward, then flatten the top with your spoon.
If there isn't enough filling, add more and start over. I know it's hard to explain in writing, and I do plan to release a video eventually, but for now you'll have to make do.
Top each dumpling with a few small pieces of carrot.
Steam for about 12 minutes.
Notes
Can I freeze my siu mai?Yes, BEFORE COOKING. They keep for about 1 month in the freezer. The process is simple:
Spread the siu mai out on a large tray, spacing them well, and freeze for 2 hours.
Once frozen, transfer them to a plastic bag. This prevents them from sticking together.
Let them thaw completely in the fridge before using. In short, take them out of the freezer the night before.
