+# How to Make Braised Chicken with Mushrooms
+
+Braised Chicken with Mushrooms is a delicious dish that pairs perfectly with rice. The ingredients are simple and the cooking process is easy to master.
+
+Estimated Cooking Difficulty: ★★★
+
+## Essential Ingredients and Tools
+
+- Chicken legs
+- Shiitake mushrooms (dried shiitake mushrooms are best)
+- Green bell peppers
+- Ginger slices
+- Dried chili peppers
+- Salt
+- Cooking wine
+- White pepper powder
+- White sugar
+- Soy sauce
+- MSG
+- Potatoes (optional)
+
+## Measurements
+
+- Chicken legs = 2 pieces
+- Shiitake mushrooms (dried shiitake mushrooms are best) = 5 pieces
+- Green bell peppers = 2 pieces
+- Ginger slices = 2 slices
+- Dried chili peppers = 5 to 6 pieces
+- Salt = 10g
+- Cooking wine = 10ml
+- White pepper powder = 5g
+- White sugar = 5g
+- Soy sauce = 5ml
+- Potatoes = 1 piece (optional, helps thicken the sauce)
+
+## Instructions
+
+### Preparation Phase
+
+- Wash the chicken legs and cut them into chunks approximately **4cm** in size.
+- Slice the ginger and cut the dried chili peppers into **small rings**.
+- Slice the shiitake mushrooms and cut the green bell peppers into thin, **horseshoe-shaped** strips. If using dried shiitake mushrooms, wash off the dust, soak them overnight, and reserve the soaking water.
+- If using potatoes, cut them into **irregular chunks** similar in size to the chicken pieces.
+
+### Stir-frying Phase
+
+- Make caramelized sugar: Pour a base layer of oil into the wok. Add the white sugar while the oil is still cold. (**This step has a certain level of difficulty; beginners can skip this and proceed to stir-frying the chicken, using dark soy sauce as a substitute for color.**)
+- Heat over low heat. As the oil temperature rises, the white sugar will melt and turn a darker brown. Stir continuously during this process to prevent burning.
+- Quickly add the chicken chunks, increase the heat to high, and stir-fry rapidly! Add the cooking wine and continue stir-frying for a moment.
+- Add the ginger slices and dried chili peppers.
+- Add the soy sauce and stir-fry until evenly mixed.
+- Pour in the shiitake mushroom soaking water or clear water, ensuring the liquid is sufficient to cover the chicken.
+- Add the sliced shiitake mushrooms, white pepper powder, salt, and potatoes.
+- Stir-fry evenly, cover the pot, and simmer over medium-low heat for **15–20 minutes**. If available, transfer to a clay pot for better results.
+- Once the chicken is tender and the sauce has thickened (do not reduce the sauce until it is completely dry), add the green bell peppers.
+- Add the MSG, stir-fry briefly to mix, and turn off the heat. The green bell peppers should be just cooked through; do not overcook them.
