+# Steaming
+
+## Methods
+
+### Steamer
+
+A steamer features a multi-tiered structure. The bottom layer holds water, and the heat from the steam generated when the water boils is used to cook the food in the upper tiers.
+
+Add an appropriate amount of water to the bottom layer of the steamer — place the food in the upper steaming rack — place the steamer on the heat source.
+
+### Wok
+
+If you do not have a steamer and only have a standard wok (not a frying pan), you can place a trivet at the bottom of the wok and add enough water to achieve a similar steaming effect.
+
+Add sufficient water to the bottom of the wok — place the trivet inside — place the food on the trivet — turn on the heat and cover.
+
+## Precautions
+
+* Since the heat source is steam, the bottom of the food in the lower tier may become soggy. You can place a steaming cloth under the food to prevent this. Alternatively, you can create a simple makeshift rack for the food using chopsticks.
+* You can use smart devices to set a timer to remind you to turn off the heat, preventing the pot from boiling dry due to forgetfulness.
+* During the steaming process, pay attention to the remaining water level in the bottom area, **especially when using a wok**, to avoid dry-boiling and potential safety hazards.
+* (Optional) When steaming food in a wok, you can place a steaming tray on top of the trivet.
