No, people should not put cream or any dairy products directly into a pressure cooker. Pressure cookers are designed to cook food with the use of water or other liquids to create steam and build pressure, which helps in faster cooking.
When cream or dairy products are exposed to high heat and pressure, they can curdle or separate, resulting in an undesirable texture and flavor. Additionally, there is a risk of the cream foaming or clogging the pressure release valve, which could be dangerous.
If you want to use cream or dairy-based ingredients in a recipe that requires pressure cooking, it's best to add them after the pressure cooking process is complete. You can incorporate the cream into the dish during a subsequent step, such as when sautéing or simmering after releasing the pressure.
Always follow the specific instructions and guidelines provided in your pressure cooker's user manual and the recipe you are using to ensure safe and delicious cooking results.
