Preparing the filling: Finely chop the Belgian endive and mix it in a bowl with the chicken mince, garlic, ginger, fish sauce, pepper, and salt. Knead well together.
Forming the dim sums: Take a dim sum wrapper, scoop a teaspoon of the filling into the center. Lightly moisten the edges of the wrapper and fold it closed into a half-moon shape. Press the edges firmly.
Making the dip: Mix all the ingredients for the sesame soy sauce in a bowl.
Steaming the dim sums: Line a steamer basket with a leaf of Belgian endive to prevent sticking. Place the dim sums apart in the basket and steam them for about 5 minutes until cooked.
Serving: Serve the dim sums immediately, along with the dipping sauce. Dip and enjoy!
Tips
Extra taste: Add a pinch of chili or a little coriander to the filling if you like spicy. No dimsum sheets? Use wonton sheets or make a simple dough of flour and water yourself. Steam basket alternative: no steam basket? Use a colander above a pan of boiling water with lid.
