Here's a clever product that's being sold by Oishi & Associaties in Japan. You know those sandwiches that you always wanted to stuff in your toaster but couldn't because your mom told you the cheese would drip and make a mess (or was as that just me?) The TOASTit bag is your workaround, letting you throw all kinds of crazy foods into your toaster without any concern for the mess afterwards.
Made from teflon, TOASTit bags cleverly take advantage of teflon's heat resistance to force your toaster to accept more than just toast. The bags look about standard toast-size, measuring 6.2 x 7.9 inches (16 x 20 cm). They can withstand temperatures of up to 260℃, and can be easily cleaned using soap and water or inside your dishwasher.
And it's not just for toast either. You can cook all sorts of things in TOASTit bags, ranging from chicken and fish to fresh vegetables such as asparagus.
Because the bags are transparent, you can easily see inside to check when your food is done. They should be used open-side up in order to let hot steam from the food escape while the natural flavor and nutrients will be kept inside.
And since TOASTit is made from non-stick teflon, it doesn't require you to use any oil or butter. It is reusable (up to 50 times), but be sure to keep sharp utensils away from it as it's easy to tear.
Oishi & Associates has TOASTit listed as 840 yen (or about $9.20) for a pack of two bags. For shoppers outside of Japan who would like to order, you might also find it available on Amazon.
