Pressure Cooker vs Canner: Which is the Best Option for Your Cooking Needs?

Pressure cookers and canners are both essential tools for home cooks who want to preserve food safely and efficiently. But what’s the difference between these two appliances? And which one is right for you? In this comprehensive guide, we’ll explore the key differences between pressure cookers and canners, so you can make an informed decision.

Pressure Cooker vs Canner: Key Differences

1. Purpose

• Pressure cooker: Designed to cook food quickly and evenly under high pressure.
• Canner: Designed specifically for canning food, which involves heating it to a high temperature to kill harmful bacteria.

2. Pressure

• Pressure cooker: Can reach pressures of 10-15 psi (pounds per square inch).
• Canner: Can reach pressures of 11-15 psi (for pressure canning) or 5-10 psi (for water bath canning).

3. Temperature

• Pressure cooker: Reaches temperatures up to 250°F (121°C).
• Canner: Reaches temperatures up to 240°F (116°C) for pressure canning and 180-212°F (82-100°C) for water bath canning.

4. Time

• Pressure cooker: Cooks food in a fraction of the time compared to traditional methods.
• Canner: Requires longer processing times to ensure the food is sterilized.

5. Safety Features

• Pressure cooker: Typically has multiple safety features, such as a pressure release valve and locking lid.
• Canner: Usually has a built-in pressure gauge and safety valve.

6. Versatility

• Pressure cooker: Can be used for a wide variety of cooking methods, including pressure cooking, browning, steaming, and slow cooking.
• Canner: Primarily used for canning food, but can also be used for other tasks, such as steaming or boiling.

Which One is Right for You?

The best choice for you depends on your specific needs.

• If you want to cook food quickly and easily: A pressure cooker is a great option.
• If you want to can food safely: A canner is essential.
• If you want versatility: A pressure cooker that can also can food is a good choice.

Tips for Choosing a Pressure Cooker or Canner

• Consider the size: Choose a size that meets your needs and the amount of food you typically cook or can.
• Check the safety features: Look for models with multiple safety features, such as a pressure release valve and locking lid.
• Read reviews: Research different models to see what other users have to say about them.
• Consider your budget: Pressure cookers and canners range in price from affordable to high-end.

How to Use a Pressure Cooker or Canner Safely

• Follow the manufacturer’s instructions carefully: Each model may have specific instructions for use.
• Never overfill the appliance: This can cause dangerous pressure buildup.
• Use the correct pressure for the food you are cooking or canning: Different types of food require different pressures.
• Always check the pressure gauge before using: Make sure the pressure is correct before starting to cook or can.
• Be aware of the potential for steam burns: Use caution when opening the pressure release valve or lid.

Beyond the Basics: Advanced Techniques

• Pressure canning: This method uses a pressure canner to heat food to a high temperature to kill harmful bacteria.
• Water bath canning: This method uses a water bath to heat food to a lower temperature, which is suitable for high-acid foods.
• Sous vide: This technique uses a pressure cooker to cook food in a vacuum-sealed bag at a precise temperature.

Troubleshooting Common Issues

• Food is undercooked: Increase the cooking time or pressure.
• Food is overcooked: Decrease the cooking time or pressure.
• Pressure cooker or canner is not heating up: Check the power source and make sure the appliance is turned on.
• Steam is leaking from the pressure cooker or canner: Check the gasket for damage and make sure the lid is properly sealed.
