Iris Ohyama Kitchen Chef Thermal Cooker: How It Works & Recipes

Iris Ohyama Kitchen Chef Thermal Cooker (Japanese Edition)

One of the safest and most energy-efficient ways to cook: bring the inner pot to the boil for just 15 minutes, then let the vacuum outer pot finish the job by heat retention — no power, no flame, no watching the stove.

Think of it as a slow cooker that cuts energy use by up to 80%. Heat your meal for 15 minutes in the morning, and dinner is ready when you get home from work. With no cord or heat source needed for the insulation stage, it's also perfect for road trips, camping, and caravans.
