This is not an authentic recipe for mapo tofu. It’s adapted from a dish that my mom always makes when cooking tofu.
First, add 1-2 tbsp. vegetable oil in a heated wok or pan. Then saute until fragrant 1 tbsp. finely chopped ginger, 2 cloves garlic finely minced and 1 small finely chopped onion. Add in 1 lb of ground beef and cook until brown.
While your meat is cooking whisk in a small bowl 1/4 cup cooking sake, 2 tbsp. oyster sauce, 2 tbsp. sweet chili sauce and 1 tsp. sesame oil. Then slice one block of silken tofu into small cubes then set these aside.
When meat is done pour in your sauce and mix to combine. Then add your cubed tofu and cook until everything is heated through and sauce is thickened. Garnish with chopped cilantro or green onions before serving.
