Fenggan

Fenggan is a traditional Chinese method for drying and preserving food. It involves hanging food items, such as meat or vegetables, in a well-ventilated area to remove moisture and prevent spoilage.

Imagine when you take a bath and use a towel to dry yourself. Just like how the towel absorbs the water from your body and helps dry you off, fenggan is like a special way of drying food to make it last longer.

To make fenggan, first, you need to choose the food you want to dry. It can be things like fish, meat, or even fruits and vegetables. Then, you prepare the food by cutting it into small pieces or thin slices, so they can dry more easily.

After preparing the food, you need to find a good place to hang it. This place should be clean and have good air circulation. It can be outside, like in a garden or on a balcony, or inside a room with windows open. The key is to let the air flow freely around the food.

Next, you hang the food on special hooks or strings, making sure they don't touch each other. This allows the air to pass around each piece, helping the drying process.

Now, you have to be patient because drying food can take some time. It can be days or even weeks, depending on the type of food and the weather. You might need to check on the food regularly to make sure it's drying properly and not getting spoiled.

During the drying process, something amazing happens! The moisture in the food starts to evaporate into the air, just like when water turns into steam. This is what helps the food become dry and last longer without spoiling. It's almost like the food is becoming lighter as it loses its water!

Once the food is completely dry, it will look different from when you started. For example, if you dry fruit, it will become smaller, lighter, and feel a bit tougher. Don't worry, though, because the taste of the food can actually become more concentrated and delicious!

Now, you can store your dried food in a cool, dry place, like a pantry. It will stay good for a long time, and you can eat it whenever you want. You can even use it in cooking to add flavor to your dishes. The best part is that because it's dried, you don't have to worry about it going bad quickly.

So, fenggan is like a special way of drying food to make it last longer and taste yummy. It's like the food is taking a bath of air instead of water, and the air helps dry it out. Then, you can keep it and eat it whenever you want.
