Arnest Co., Ltd., a company that plans and sells household items and lifestyle products, will release a new product, the "Thermal Cooking Pot Cork Cook 18cm," on January 30, 2026, through select specialty stores, co-ops, online retailers, and their official e-commerce site.
Thermal Cooking That Eliminates the Need for Constant Attention
In busy daily life, simmered dishes are often a concern due to "heat control" and "utility costs." The "Thermal Cooking Pot Cork Cook 18cm" addresses these concerns as a cooking pot that continues cooking even after the heat is turned off.
After initially heating the pot on the stove, you can simply rely on the insulation power of cork. It achieves a slow-simmered finish as if cooked over low heat, all through a hands-free approach to simmering.
Set It and Forget It With Thermal Cooking
Simply place ingredients in the pot, heat it on the stove, and then set it in the cork container. Even without continuous heating, the pot maintains a temperature similar to gentle simmering over low heat.
Because it doesn't require strong continuous heating, there's no worry about boiling over or burning, and it prevents ingredients from falling apart while allowing heat to penetrate thoroughly. With no need to adjust heat levels or constant monitoring, this is a truly "hands-free" thermal cooking pot.
Cork's Insulation Power Maintains 70°C for Approximately 2 Hours
The dedicated cork container utilizes the insulating properties of cork material. When the heated pot is set inside, it prevents internal heat from escaping and maintains a temperature of approximately 70°C for about 2 hours. Compared to regular pots, the temperature drops more gradually, allowing efficient use of residual heat after cooking. As the temperature slowly decreases, flavors thoroughly permeate the ingredients.
Cook Another Dish While Thermal Cooking Is in Progress
Since the stove becomes available during thermal cooking, you can prepare stir-fries or other dishes in the meantime.
You can also take your eyes off the simmering pot, allowing you to allocate time to other cooking tasks or household chores, improving overall household efficiency.
Made in Tsubame-Sanjo With Supervised Recipe Included
The pot body is manufactured in Tsubame-Sanjo, Niigata Prefecture, an area known for metalworking. It features durability and ease of use that provides peace of mind for daily cooking.
Additionally, it comes with recipes supervised by Natsuko Fujiwara, a nutritionist and Kitchen Tool Meister. The recipes take advantage of thermal cooking characteristics, making them easy for beginners to follow without failure, and they can be put into practice from the day the product arrives.
