Half a tablespoon of chopped onion and garlic, two tablespoons of star anise soy sauce, one tablespoon of pillar sauce, one tablespoon of sugar, one teaspoon of monosodium glutamate, half a teaspoon of allspice powder, half a teaspoon of soy sauce and one teaspoon of rose wine.

It seems that these seasonings are more difficult to find than barbecued pork sauce, so let's stay here. It may be useful.

Star anise soy sauce: star anise, a bowl of soy sauce.

Practice: mix the two and soak for two days.

I hope it helps you.
