Introduction to Pressure Cooking
Before diving into the specifics of what cannot be cooked in a pressure cooker, it’s beneficial to have a basic understanding of how pressure cookers work and the principles behind pressure cooking. Pressure cookers are sealed vessels that use steam pressure to cook food faster than traditional methods. The steam builds up inside the cooker, increasing the pressure and temperature, which in turn accelerates the cooking process. This method is particularly good for cooking tougher cuts of meat, legumes, and a variety of grains.
Safety Considerations
One of the primary reasons some foods are not recommended for pressure cooking is safety. Overheating and over-pressurization can lead to the explosion of the cooker, posing a significant risk to the cook and bystanders. Additionally, certain foods can foam or suds excessively when heated, which can clog the pressure cooker’s valve and lead to dangerous situations. It’s crucial to be aware of these risks and take necessary precautions.
Risk Assessment
When assessing the risk of cooking a particular food in a pressure cooker, consider its density, water content, and tendency to expand or foam. Foods with high water content or those that are highly expansive can be risky, as they can lead to a sudden increase in pressure. Similarly, foods that are prone to foaming, such as dairy products and certain types of grains, can block the valve and prevent the release of excess steam, leading to a buildup of pressure.
Foods to Avoid in a Pressure Cooker
While pressure cookers are incredibly versatile, there are certain foods that are best avoided due to their texture, composition, or the risk they pose.
Delicate Fish and Some Seafood
Delicate fish and certain types of seafood, such as sole or flounder, can become overcooked and ** mushy due to the high pressure and temperature. These foods are typically better cooked using methods that allow for more control over cooking time and temperature, such as pan-frying or baking**.

Creamy sauces and dairy products can curdle or separate under high pressure, leading to an undesirable texture. Furthermore, dairy can foam excessively, which poses a risk of clogging the valve. While some recipes may incorporate dairy towards the end of cooking, adding it at the beginning is generally not recommended.
Cereals and Grains That Foam
Certain cereals and grains, such as oats and quinoa, can produce a significant amount of foam when cooked under pressure. This can lead to safety issues, as mentioned earlier. While these grains can be cooked in a pressure cooker, it’s essential to be cautious and monitor the cooking process closely.
Cooking Methods That Don’t Suit Pressure Cookers
Beyond specific foods, there are also certain cooking methods or goals that are not well-suited for pressure cookers. These include browning or searing, which are crucial steps in many recipes for developing flavor and texture. Pressure cookers are designed for moist-heat cooking and do not allow for the same level of browning as dry-heat methods like pan-frying or grilling.
Alternative Cooking Methods
For foods and dishes that are not suitable for pressure cooking, there are often alternative methods that can achieve similar or even better results. Slow cookers, for example, are great for cooking tough meats and stews over a long period, allowing for tenderization without the risk of overcooking. Instant pots with sauté functions can also be used for browning before switching to pressure cooking mode, offering a compromise for those who want the benefits of both worlds.
Choosing the Right Tool
Ultimately, the choice of cooking method depends on the desired outcome, the type of food being cooked, and personal preference. Understanding the capabilities and limitations of each cooking tool, including pressure cookers, is key to achieving culinary success and safety in the kitchen.
