If you heat it warmly, you can make sweet and salty sweet potatoes. Here are three convenient items that you can easily cook in a microwave or toaster oven.

Eye wrap

"Eye Wrap " (Iwatani Material), which has a heat resistance of 120 degrees and a cold resistance of -30 degrees, is a plastic bag that can be used as both a wrap and a freezer bag. One of the reasons why it is supported is that the cost performance is very good at about 3 yen per sheet.


If you put sweet potatoes in this eye wrap and heat it in the microwave, it's easy to make sweet potatoes. Finished without uneven heating or dryness. It is also a good idea to crush it in a bag and process it into a chakin squeeze or sweet potato.

Stone-grilled potato black sunfoil

"Ishiyaki Imo Black Sun Foil " (former product name: Ishiyaki Imo Black Foil) developed by Toyo Aluminum Echo Products is an aluminum foil with special black processing on the outside to improve heat absorption. If you wrap the sweet potatoes in this "stone-grilled potato black sunfoil" and then put them in the toaster oven, the heating time will be shortened. The core is cooked to give it a chewy, moist texture.



It was renewed and released in August 2020, and the black side has been changed to a fun grilled pattern. The size has also been changed from 3m to 3.6m, and about 18 sweet potatoes with a length of 20cm can be used.

Petit pressure cooking bag

The "Petit Pressure Cooking Bag " developed by Lion is a plastic bag for microwave cooking. It has a steam outlet, and when you put the food in it and heat it in the microwave, the steam from the food convects inside. Heating proceeds while "petit pressure" is applied. With this mechanism, the finish is less uneven than when heated with a wrap or silicon steamer. It is also characterized by the fact that meat, fish and vegetables become "tasteful" in a short time.


Put sweet potatoes, water, honey, sugar, and mirin in this "petit pressure cooking bag" and chin it to make a delicious simmered dish. It is also a point that sweet potatoes can keep their beautiful shape without simmering.





Convenient goods that are easier and more finished than when using ordinary wrap or foil. If you see it at a supermarket or mail order site, why not give it a try? We also recommend steaming the sweet potatoes in a frying pan with an oven sheet.
