Marinate the pork and prawn with 1/2 teaspoon of ginger wine.
Heat pan with oil over medium heat, add garlic, minced pork, prawns, light soy sauce, sesame oil and fry for 2-3 minutes or till everything is cooked evenly.
Fill a pot 1/3 full with water, and bring to the boil.
Once boiling, reduce to low heat (barely simmering) and place the tofu inside.

Go back to the pan with water, mushrooms, stirring constantly and add pepper to taste.
Pour cornstarch over to thicken and allow it to simmer over 1 minute.
Taste and season with more salt, if required.
