+# How to Make Steamed Eggs in a Microwave
+
+A high-protein breakfast that is tender, smooth, and ready in minutes, made entirely in the microwave. Takes about 10 minutes and serves 1-2 people.
+
+Estimated Cooking Difficulty: ★
+
+## Essential Ingredients and Tools
+
+- Eggs
+- Warm water or broth
+- Salt
+- Light soy sauce (optional)
+- Sesame oil
+- Microwave-safe bowl
+- Plastic wrap or microwave-safe lid
+
+## Measurements
+
+- 2 eggs (approx. 100g of beaten egg)
+- 100-120ml warm water or broth (1.0-1.2 times the volume of the egg)
+- 1g salt
+- 2ml light soy sauce (optional)
+- A few drops of sesame oil (for garnish)
+
+Using the above conditions, calculate the ratio of raw materials to be used.
+
+## Instructions
+
+- Beat the eggs, then add the warm water/broth, salt, and soy sauce. Gently stir to combine, trying to avoid creating bubbles.
+- Strain the egg mixture into a microwave-safe bowl. If there are any bubbles on the surface, pop them gently with a toothpick.
+- Cover with plastic wrap and poke 8-10 small holes, or use a microwave-safe lid (leaving a small gap).
+- Microwave according to your power level:
+  - 700W: 1 minute 30 seconds → Check and heat for another 20-30 seconds if needed until the surface just sets.
+  - 600W: Approximately 1 minute 40 seconds to 2 minutes 10 seconds.
+  - 800W: Approximately 1 minute 10 seconds to 1 minute 40 seconds.
+- After heating, let it rest for 1 minute to allow residual heat to fully cook the center.
+- Drizzle with sesame oil and sprinkle with chopped green onions before serving.
+
+> Different power levels and containers will affect cooking time. It is recommended to heat in short intervals during your first attempt to find the optimal time for your specific device.
+
+## Additional Tips
+
+- The water temperature should be 40–50℃; do not use water that is too hot.
+- For the best texture, keep the egg-to-liquid ratio between 1:1 and 1:1.2.
+- Covering with plastic wrap and poking holes prevents the surface from bursting or developing a honeycomb texture.
+- Straining significantly improves the smoothness of the final dish.
+- If the surface bubbles or releases water, it has been overcooked; simply reduce the heating time next time.
