To Prep
In a large bowl, combine the pork and prawns with the Shaoxing wine, soy sauce, sesame oil and salt and pepper.
Place a teaspoon of the filling in to the centre of one of the wrappers and then bring in the sides and gently squeeze to set the shape.
To ensure that the siu mai stands, make sure that the bottom is relatively flat.
If desired, place some of the fish roe on to the top of the siu mai.
Repeat this process until there is no more filling left.
To Cook
Set up a steamer with enough water to cook all of the siu mai and line with baking paper to stop it from sticking to the steamer.
Steam the siu mai in batches for at least 8 minutes or until they are cooked through and then serve!
