饺子是中国传统的美食之一，制作过程中有一个特别的步骤，那就是在煮饺子时要加入凉水。为什么要这样做呢？下面就让我们一起来探究一下。

首先，我们要了解饺子的特点。饺子属于面食类，其外皮是由面粉和水混合而成的，因此在煮的过程中容易粘连在一起。如果我们直接将水烧开后放入饺子，由于水温较高，饺子粘连的可能性会增加，很容易导致饺子煮破或者粘底。因此，加入凉水可以有效地避免这个问题。

Secondly, adding cold water also helps to maintain the chewy texture of the dumpling skins. When we add cold water to the pot, it reduces the overall temperature and prevents the water from boiling too rapidly. This gentle cooking process allows the dumpling skins to cook evenly and become tender, while still maintaining their chewiness. If we were to use boiling water instead, the high heat would cause the skins to become soft and mushy, resulting in a less satisfying texture.

其次，加入凉水还有助于保持饺子皮的嚼劲。当我们向锅中加入凉水时，它会降低整体温度，防止水太快地煮沸。这种温和的烹饪过程可以使饺子皮均匀煮熟，保持其柔软的同时又能保持嚼劲。如果我们使用沸水，高温会导致饺子皮变软糊状，从而导致口感差。

Thirdly, the addition of cold water helps to maintain the structural integrity of the dumplings. The sudden contact with boiling water can cause the dumplings to expand too quickly, which may lead to them bursting open. By adding cold water, we can gradually increase the temperature of the water, allowing the dumplings to cook evenly without bursting.

第三，加入凉水有助于保持饺子的形状完整性。饺子与沸水的突然接触会导致饺子膨胀过快，可能导致饺子破裂。通过加入凉水，我们可以逐渐增加水的温度，使饺子均匀煮熟而不破裂。

In addition, adding cold water also helps to regulate the cooking time of the dumplings. When we add cold water, it lowers the temperature of the boiling water, which in turn extends the cooking time. This allows the fillings inside the dumplings to cook through properly, ensuring that they are safe to eat.

此外，加入凉水还有助于控制饺子的烹饪时间。当我们加入凉水时，水的温度会降低，从而延长煮饺子的时间。这使得饺子内的馅料能够充分煮熟，确保食用安全。

In conclusion, adding cold water when boiling dumplings is an important step in ensuring a successful batch of delicious dumplings. Not only does it prevent the dumplings from sticking together, but it also helps to maintain their chewy texture, structural integrity, and allows for proper cooking of the fillings. So next time you make dumplings, don't forget to add cold water to the pot and enjoy a perfect batch of dumplings!

总之，在煮饺子时加入凉水是确保一锅美味饺子成功的重要步骤。它不仅可以防止饺子粘连，还有助于保持其柔软的口感、形状完整性，并可以使馅料煮熟。所以下次做饺子时，别忘记往锅里加入凉水，品尝一锅完美的饺子吧！

英文翻译对照：

Firstly, we want to understand the characteristics of dumplings. Dumplings are a type of traditional Chinese food made from a mixture of flour and water, which makes them prone to sticking together during cooking. If we were to put the dumplings directly into boiling water, the high temperature would increase the likelihood of them sticking together, causing them to break apart or stick to the bottom of the pot. Therefore, adding cold water can effectively avoid this problem.

Secondly, adding cold water also helps to maintain the chewy texture of the dumpling skins. When we add cold water to the pot, it reduces the overall temperature and prevents the water from boiling too rapidly. This gentle cooking process allows the dumpling skins to cook evenly and become tender, while still maintaining their chewiness. If we were to use boiling water instead, the high heat would cause the skins to become soft and mushy, resulting in a less satisfying texture.

In conclusion, adding cold water when boiling dumplings is an important step in ensuring a successful batch of delicious dumplings. Not only does it prevent the dumplings from sticking together, but it also helps to maintain their chewy texture, structural integrity, and allows for proper cooking of the fillings.
