How to make it
Heat up oil in a pan and stir-fry onions, mushrooms, char siu and yellow chives. Add seasoning mix and cook until sauce thickens. Set filling aside to cool and divide into 20 portions.
Beat lard, butter and sugar together until light and fluffy. Fold in sieved flour. Add water to form a soft dough. Knead until smooth. Form the dough into a long roll. Divide into 20 equal portions and flatten each portion to form rounds.
Wrap each portion of filling with a piece of dough to form puffs. Glaze with beaten egg.
Bake pork puffs at 190°C for 15-20 mins until golden brown and cooked.
