First is a disclaimer that this not "authentic". I have 2 recipes that appear to be more authentic but both are different in some key ingredients (Szechwan peppercorns & cayenne vs. chili paste with garlic). Mine is more similar to the later and I go with a greater volume of sauce to flavor the steamed rice we serve it with. I also add tomato sauce from the can because I like the color and I don't keep the authentic "brown bean sauce" on hand. Chinese dishes often use ketchup, you could probably substitute that or use 3 Tablespoons of Brown Bean Sauce instead of the tomato ingredient. One recipe also called for sesame oil (2 tsp) which sounds good to me.
Mince 2 cloves of garlic.
Mince 1 Med-Large slice ginger (about 1 Tablespoon)
Slice thinly 2 green onions.
In a wok with a small amount of peanut or flavorless oil lightly brown 8-10 ounces of ground turkey or the authentic ground pork over medium heat then add the garlic, ginger and green onions. Continue cooking for a few minutes then add:
3 tablespoons soy sauce
3 tablespoons Chinese rice wine (cooking wine)
Continue cooking until liquid has reduced.
In a measuring vessel (approx 5 cup size) add and whisk the following:
3 cups chicken stock
4 oz canned tomato sauce
2 teaspoons Sriracha (a Vietnamese hot chili garlic sauce) or substitute the same quantity of Chinese chili sauce with or without garlic)
1 teaspoon sugar and 4 tablespoons cornstarch. Blend thoroughly.
Now add this mixture into the wok with the meat mixture and heat over medium until thickened.
While this is heating, rinse then dice and drain 2 tubs of tofu and add to the wok.
You may use firm, medium or silken as you prefer. Leave heat on to warm the tofu.
