Question: sized of cooking surface for 8" and 9 1/2"?
Document: We use it on a electric stove since about 1 1/2 years now and this is by far now my favorite pan. Nothing sticks, it heats evenly and it easily can be cleaned, no scrubbing, etc. Worth every penny! Just fantastic! Tres bonne
This is a quality product. I have never had an issue with Le Creuset and would by it again. This size is perfect for cooking 2 eggs in the morning.
I use this all the time. We are now only 2 in the house so frequently doing small quantities of onions, pine nuts and such
Great cookware. Non Stick surface is perfect. High quality, worth the price. I use it mainly for breakfast, ideal 2egg skillet.
Furthermore, we don't need to worry about harmful chemicals leeching into our food (we hope).This really is the best non-stick surface I have ever cooked on, and, so far, lives up to all of the claims.
After reading reviews of all 8-inch pans, I chose this and am VERY happy I did. It is very well made and well balanced, and I'm sure will last many years.
My old lids from the 8" All Clad fit on these so I did not order a separate lid. We will be replacing all of our pans with these. They are robust without being too heavy. They seem a little smaller than our All Clads but not by much. I love it and would highly recommend.
I use these pans for cooking omelettes. They work great. The completely meet my expectations and I recommend them to anyone.
We just purchased this pan because we liked the idea that the exterior is non-stick as well as the interior. We have used their enameled cookware in the past and found it very difficult to keep the enamel clean. This one may not be as pretty but it sure should be a year from now. In addition, the pan comes with a 10 year warranty for the cook surface. It also has an extra thick flat bottom which is great for our flat range top.
I used only coated utensils and still the surface was scratched after a couple of months of use. The surface also gradually became carbonized but that was because I had not yet learned that you have to wipe these pans with a paper towel after each use to remove all residue that might carbonize with the next heat cycle. Wiping is no big deal as long as the pan is in good condition and nothing sticks but when scratches develop, food will stick to them and wiping becomes more difficult.
Answer: I have the 8" with a 6" flat cooking surface.
