What is the difference between a Steam Over Cooking Pot and a pressure cooker?

When it comes to kitchen appliances, steam over cooking pots and pressure cookers are two popular choices that offer distinct cooking methods and benefits. As a supplier of steam over cooking pots, I am often asked about the differences between these two types of cookware. In this blog post, I will delve into the characteristics, advantages, and disadvantages of steam over cooking pots and pressure cookers to help you make an informed decision for your kitchen.

How They Work

Steam Over Cooking Pot

A steam over cooking pot, also known as a steamer pot, operates on the principle of steam cooking. It typically consists of multiple layers or compartments that allow you to cook different foods simultaneously. Water is placed at the bottom of the pot, and as it heats up, it turns into steam. The steam rises through the layers, cooking the food gently and evenly. This method of cooking helps to retain the nutrients, flavors, and colors of the food, making it a healthy and delicious option.

There are various types of steam over cooking pots available in the market. For example, the Double Layer Steam Pot offers two separate compartments for cooking different items at the same time. The Stackable Storage Cooking Pot is not only great for cooking but also for storage, as the layers can be stacked neatly. And the Stainless Steel 1 Layer Steamer Soup Pot is perfect for making soups and steaming single items.

Pressure Cooker

A pressure cooker, on the other hand, uses high-pressure steam to cook food quickly. It is a sealed pot with a locking lid that traps steam inside. As the steam builds up, the pressure inside the pot increases, raising the boiling point of water. This allows the food to cook at a higher temperature than normal, significantly reducing the cooking time. Pressure cookers are equipped with safety features such as pressure release valves to prevent over - pressurization.

Cooking Time

One of the most significant differences between a steam over cooking pot and a pressure cooker is the cooking time.

Steam Over Cooking Pot

Steam over cooking pots generally take longer to cook food compared to pressure cookers. Since the cooking is done using steam at normal atmospheric pressure, the process is more gradual. For example, steaming a large batch of vegetables might take 10 - 15 minutes, depending on the type and quantity of vegetables. Cooking a whole chicken using a steam over cooking pot could take over an hour. However, this slower cooking process can be beneficial for some foods as it allows for a more gentle and even cooking, preserving the texture and nutrients.

Pressure Cooker

Pressure cookers are known for their speed. They can reduce cooking times by up to 70%. For instance, a tough cut of meat that would take several hours to cook in a regular pot can be tender and ready to eat in just 20 - 30 minutes in a pressure cooker. Beans that usually take hours to soak and cook can be cooked in a fraction of the time. This makes pressure cookers an excellent choice for busy individuals or families who want to have a home - cooked meal in a short amount of time.

Nutrient Retention

Both steam over cooking pots and pressure cookers are considered healthy cooking options, but they differ in how they retain nutrients.

Steam Over Cooking Pot

Steam cooking is a gentle method that helps to retain a high percentage of the nutrients in food. Since the food is not in direct contact with water, there is less leaching of vitamins and minerals. For example, when steaming broccoli, the vitamin C and other antioxidants are better preserved compared to boiling. The steam also helps to keep the natural flavors and colors of the food intact, making the dishes more appealing both visually and in taste.

Pressure Cooker

Pressure cooking also retains a good amount of nutrients. The short cooking time means that the food is exposed to heat for a shorter period, which helps to minimize the loss of heat - sensitive vitamins such as vitamin C and B - vitamins. However, some nutrients may still be lost due to the high - pressure environment. Additionally, the high - pressure steam can break down the cell walls of the food, making it easier to digest.

Versatility

Both types of cookware offer a certain degree of versatility, but in different ways.

Steam Over Cooking Pot

Steam over cooking pots are very versatile when it comes to cooking a variety of foods. You can steam vegetables, fish, rice, and even make steamed puddings and dumplings. The multiple layers allow you to cook different components of a meal at the same time. For example, you can steam vegetables on one layer, fish on another, and rice on the bottom layer, all in one go. This makes it convenient for preparing a complete meal.

Pressure Cooker

Pressure cookers can handle a wide range of cooking tasks, including stewing, braising, boiling, and steaming. They are great for making soups, stews, and curries. You can also use them to cook large cuts of meat, beans, and grains quickly. Some pressure cookers come with additional functions such as sautéing, which allows you to brown the meat or vegetables before cooking under pressure.

Safety

Safety is an important consideration when using any kitchen appliance.

Steam Over Cooking Pot

Steam over cooking pots are generally considered safe to use. They operate at normal atmospheric pressure, so there is no risk of over - pressurization. However, you still need to be careful when handling the hot pot and steam. Make sure to use heat - resistant gloves when removing the lid or the food from the pot to avoid burns.

Pressure Cooker

Pressure cookers have come a long way in terms of safety features. Modern pressure cookers are equipped with multiple safety mechanisms such as pressure release valves, locking lids, and over - pressure protection. However, if not used correctly, there is still a risk of steam burns or even explosions. It is essential to follow the manufacturer's instructions carefully when using a pressure cooker, including proper sealing of the lid, correct pressure settings, and safe pressure release.

Cost

The cost of steam over cooking pots and pressure cookers can vary depending on the brand, size, and features.

Steam Over Cooking Pot

Steam over cooking pots are generally more affordable, especially the basic models. They are made of various materials such as stainless steel, aluminum, or ceramic. The price can range from relatively inexpensive options for simple single - layer steamers to more expensive multi - layer and high - quality models.

Pressure Cooker

Pressure cookers tend to be more expensive, especially those with advanced features such as digital controls and multiple cooking functions. However, considering the time - saving and versatility they offer, they can be a worthwhile investment for many households.

Conclusion

In conclusion, both steam over cooking pots and pressure cookers have their own unique advantages and disadvantages. Steam over cooking pots are great for gentle, nutrient - rich cooking and are ideal for those who have more time to prepare meals. They are also very versatile for cooking a variety of foods and are relatively safe and affordable. On the other hand, pressure cookers are a time - saving option, perfect for busy individuals. They can cook tough foods quickly and are also versatile in terms of the types of dishes they can prepare.
