Question: are the egg inserts non stick material or just the stainless steel?
Document: Even the large knob on top of the clear lid (very attractive lid) remained hot long after I'd finished eating the poached eggs.Although I used ghee to lubricate the egg inserts, cleaning them was labor intensive. I'm willing to do this because I would not consider non-stick anything but it took a lot of time to remove the crusted egg white from the stainless steel inserts.So, why did I give this product five stars? You already know. The eggs were gorgeous and delicious.
I received my Norpro egg poacher a couple weeks ago and am very happy with it. It's made of stainless steel and for more even heat distribution the bottom is constructed of a stainless-aluminum-stainless sandwich. The description says the individual egg cups are aluminum with a stainless steel coating and that is wrong. The cups are stamped stainless steel, pure and simple - no aluminum here and no non-stick coating either.
This is a great egg poacher. I have had it for a couple years now, and it has held up well. Features I particularly appreciate are the stainless steel egg holders (rather than Teflon) and the glass lid. As the egg holders have no non-stick coating, you must coat them with something before adding the eggs. I initially used Pam spray, which worked OK, but there was still a little sticking. I now use olive oil, which works great and is probably healthier.
When I found out that non stick cooking surfaces caused cancer, I reluctanly put away my egg poacher and started looking for one that didn't have the non stick egg cups. I might add that I looked for a long time before I found this one. I highly recommend this stainless steel egg poacher to anyone who wants a product that not only cooks poached eggs perfectly, but does it the healthy way. I couldn't be more pleased.
I searched quite a while to find the perfect truly stainless steel egg poacher, and this one was worth every penny. It is very high quality and will last many years to come.Add 3 cups of water, bring to a boil, toss on the cover and wait about 4 minutes (high altitude) for perfect poached eggs.To make them non-stick, use a small basting brush and some of your favorite cooking oil on the egg cups first. They will slide right out!
I have been looking for a long time (a few years) for a stainless steel egg poacher without the &#34;non-stick&#34; coating. Not finding one, I learned how to poach using water and vinegar in a saucepan. Then recently I saw this Norpro Stainless Steel Egg Poacher in Amazon and was thrilled. However, I really needed one that would work on an induction burner. The question and answers on this were conflicting, so I decided to go ahead and get it.
I love this egg poacher because it's stainless steel and makes excellent poached eggs. I didn't want one of the non-stick models for obvious reasons. So you will next ask, how do you keep the eggs from sticking in the stainless steel egg cups? Well, I found the solution, after my first attempt failed. The first time I used the egg poacher, I took one of the reviewers advice and used melted butter. It didn't work as well as I had hoped.
I'm glad I spent the time searching for a quality stainless steel pan with stainless steel cups since I didn't want any more unhealthy, toxic non-stick pans! Yes, you DO get little white spots on the large pan but it doesn't matter at all. This pan has 5 cups - I wish it had 6, but this works.
Good quality, nicely weighted. Looks like its going to last a long time. Love that the cups are stainless WITHOUT the non-stick coating. Eggs come out easily and cook evenly. So much better than microwaving or slipping an egg in hot water.
This egg poacher works great. I purchased the stainless egg cups because I didn't want the non-stick coating. The glass lid lets you easily monitor how the eggs are cooking. The plastic knobs allow you to easily remove the cups. As both the instructions and the other reviews note, these knobs can get hot so don't grab them with bare hands immediately after removing the lid.
Answer: They are stainless steel.  NOT the toxic non stick material.
