+# How to Make Stir-Fried Cauliflower
+
+Stir-fried cauliflower is a common home-style vegetarian dish. It is rich in vitamin C and dietary fiber, with a crisp and tender texture. The recipe is simple and easy to master, making it a quick stir-fry. Beginners can typically complete it in just 15 minutes.
+
+Estimated Cooking Difficulty: ★★
+
+## Essential Ingredients and Tools
+
+- Cauliflower
+- Garlic
+- Salt
+
+## Calculation
+
+Determine how many servings you want to make before each preparation. One serving is exactly enough for 2 people (as a side dish).
+
+Per serving:
+
+- Cauliflower: approx. 300 g (about 1/2 of a medium-sized cauliflower head)
+- Garlic: 2-3 cloves
+- Salt: 3 g
+- Cooking oil: 15 ml
+- Drinking water: 50 ml (for the stir-frying process)
+
+## Instructions
+
+- Wash the cauliflower and break it into small florets using a knife or your hands. Slice the thick stems and set aside.
+- Peel the garlic and slice it into thin pieces. Set aside.
+- Add 1000 ml of drinking water to a pot and bring to a boil over high heat.
+- Add the cauliflower florets and boil for **2-3 minutes** until the color lightens and the texture becomes slightly softened.
+- Remove the boiled cauliflower, drain well, and set aside.
+- Heat a wok or pan, add 15 ml of cooking oil, and heat over high heat.
+- Add the garlic slices and stir-fry quickly until fragrant.
+- Add the blanched cauliflower florets, increase the heat to medium-high, and stir-fry quickly for about **2 minutes** to ensure even heating.
+- Add 3 g of salt and continue to stir-fry evenly.
+- Pour 50 ml of drinking water along the side of the pan, cover with a lid, and simmer for **1 minute** to help the cauliflower cook through and absorb the flavors.
+- Remove the lid, stir-fry quickly to mix evenly, and serve.
+
+## Additional Notes
+
+- Blanching the cauliflower in advance shortens the stir-frying time and helps it cook through more easily.
+- Stir-frying time can be adjusted based on your preferred texture. Reduce the time if you prefer a crispier texture.
