So, a coworker related to me how his mother-in-law made an omelet by combining the raw ingredients in a plastic ziplock bag, sealing it, and boiling it in water for 14 minutes. I was a bit skeptical, but tried it last night, and it worked like a dream. It was so easy, didn't require any skill and there was absolutely no clean up required. I should add that it also tasted fantastic.
I posted on Facebook about it, and was surprised that many people hated on the idea. One of the main criticisms was that there are fears that toxic chemicals could leech out of the bag into the food.
I did some searching online, and saw some posts that the Boy/Girl Scouts used to use this method for camping, but no longer recommend it. And there are a lot of sites that reference a supposed University of Illinois release that says:
They [Ziploc] do not recommend using any ZIPLOC® brand Bag in boiling water, or to “boil” in the microwave. ZIPLOC® brand Bags are made from polyethylene plastic with a softening point of approximately 195 degrees Fahrenheit. By pouring near boiling water (water begins to boil at 212 degrees) into the bag, or putting the bag into the water, the plastic could begin to melt. Might I add that eggs and cheese have fat which gets much hotter than water thus the likelihood of melting the plastic increases.
This is where I get skeptical. Someone doesn't know basic physics if they think that the fat is somehow going to get hotter than the water in which it is boiling. Huh?! Not to mention that the writing style (and grammar) don't strike me as something to come out of an official University release.
So what are your thoughts on this? Does the convenience of this cooking method outweigh the potential risks? And is the risk even one that seems logical?
