Question: Are these stained or treated in any way?
Document: Though I read that clear up after a couple of uses.Other than that it's a decent bamboo steamer.I just hope it isn't chemically treated.
Have already used the steamer several times on fish, chicken and vegetables. Much healthier way to cook and my family even likes it.
I like this brand - nice size.I love Bamboo steamers. It's the best way to cook fresh green beans!Best way to get all your fresh veggies.
There isn't a healthier way to cook, period. I was always seeing these steamers in videos, but have never actually tried one. Now my kids are always asking me to make dumplings and steamed fish. They just love when I go ''ASIAN COOKING MODE''.
I have used this product 1 time so far. It steamed a whole meal in less time then it took to do it the old fashioned way. Alot less clean up as well. This is a great product if you like to cook healthy meals for your family.
I have always loved to use bamboo steamers. The food comes out juicy and so tender. I have a pan that it fits into just right. Steamed food such great flavor and is really quick to make. Its so healthy. This steamer is made very well and fits together the way it should, so the steam does not escape. It will last a very long time...
I am a cooking-impaired male. I decided (or rather, She decided) that it was time I learned to cook, so I decided to try this steamer. I can proudly say that I am on my way to becoming a fairly good cook, and She is very pleased with me! !Guys, if you have never steamed before (don't know how to cook rice) this is the steamer to buy.
Although I have not tried other bamboo steamers, I'm quite pleased the quality. I cook with this several times a week. Chicken and all kinds of fish never tasted so good and healthy. I've already purchased a 2nd steamer for my 2nd home.Fish and chicken cook in 10 minutes guaranteed! This is the healthiest way to eat.
We'll see how the other tier holds up -- I tend to only use one layer at a time, so maybe it was a case of bad luck with the one that deconstructed.UPDATE:  I emailed their web site about my falling-apart basket, and within a few hours I got an email back that a replacement was on the way. I"m upping my stars to 5: good customer service is gold.
The Joyce Chen 10-Inch Bamboo Steamer Set is all that it is touted to be. When I buy a Joyce Chen product, I expect to buy quality, and Chen's streak continues with this product. It is well made, simple to use, and offers a quick and healthy way to cook food. Also, the price was right. My only critique, and it has nothing to do with the product, it has more to do with the marketing department at Joyce Chen.
Answer: No they are not as far as I can tell. Mine looks exactly like the photo in ad.
