Learn how the Kuhn Rikon HOTPAN thermal cooker works, when to use it, and get step-by-step tips for energy-saving slow cooking without electricity.
Quick Answer
The Kuhn Rikon HOTPAN thermal cooker lets you start cooking on the stove, then finish the meal using retained heat—no electricity needed. Use it for stews, soups, and roasts when you want energy-saving, hands-off cooking.
Why Choose a Thermal Cooker?
Thermal cookers work by bringing food to a boil on the stove, then transferring the pot to an insulated outer container. The retained heat continues cooking the food slowly, without using any additional energy. This makes them ideal for busy cooks who want a tender, slow-cooked result without monitoring a flame or plugging in an appliance.
The main trade-off is timing: you need to plan ahead because the cooking process takes longer than traditional stovetop methods. However, the hands-off time is a benefit—once sealed, you can leave it safely while you attend to other tasks.
When to Use Your HOTPAN
Use the HOTPAN for dishes that benefit from long, gentle cooking: soups, stews, curries, braised meats, and even rice or grains. It's also great for keeping food warm during a meal or for taking hot dishes to a gathering.
Avoid using it for recipes that require rapid boiling or reducing liquids, as the sealed environment doesn't allow for evaporation. Also, don't use it for deep-frying or pressure cooking—those require specialized equipment.
How to Use Your HOTPAN Thermal Cooker
- Step 1: Prep and bring to a boil: Place your ingredients in the inner pot and bring them to a rolling boil on the stove, following your recipe's instructions. This ensures the food reaches a safe temperature and activates the cooking process. Check that the pot is at a full boil before moving on—a common mistake is sealing it too early, which undercooks the food.
- Step 2: Seal the pot and transfer: Immediately place the hot inner pot into the insulated outer container and close the lid securely. The tight seal traps the heat, allowing cooking to continue without any external energy source. Ensure the lid is fully locked; a loose seal lets heat escape and slows the cooking process.
- Step 3: Let it cook and check: Leave the pot sealed for the recommended time—typically 1.5 to 2 times longer than conventional cooking. After the minimum time, open carefully and check that the food is tender and cooked through. Resist the urge to peek frequently; every opening releases heat and extends the cooking time.
- Step 4: Serve or keep warm: Once cooked, you can serve directly from the pot or keep it sealed to maintain serving temperature for up to several hours. This is ideal for buffets or when serving guests at different times. If you're not serving immediately, keep the lid closed to retain warmth—no need for a chafing dish.
