Question: What are the inside dimensions of the pan?
Document: the pan worked good for me for what I wanted it to. Better than I thought it would. Will keep it.
It lived up to all my expectations. I will never use a metal pan again. which I had known about this years ago.
Definitely easy to get bread out of the pan. Easy to clean. I got this for a specific recipe.
This was my first experience using silicone baking pans, and I'm hooked! No more stuck loaves, or need for oil in the pan. Seems to be very durable.
I use this pan to make Life Changing Bread--a gluten/dairy free bread that is basically seeds and nuts; lots of fiber, and is WONDERFUL. It needs a silicone pan for baking and this works perfectly. If you are interested in a very healthy, fiber providing bread, look on the net for the Life Changing bread recipe.
My sourdough bread was always collapsing on me (for many years). Never knew when it would turn out. Well, someone told me to buy one of these silicone loaf pans and I did. Now my bread turns out great EVERYTIME. Don't know what the difference is from a metal pan, but it works. Full loafs now everytime I bake sourdough bread (or any other bread I make). Give it a try. Great price also on this pan.
After trying a 9x9 silicone pan, my wife liked it and wanted something to handle dishes like meat loaf. This orange loaf pan worked well, but quickly became stained -- probably from tomato sauce. We then tried washing it in the dishwasher but it still has several stains. If that bothers you, then try to find black silicone cookware.She recently cooked 2 loaves of banana bread at the same time -- one in this pan and one in glassware. They both came out the same -- excellent.
Quality is really good, highly recommended
Outstanding pans. I can make four perfect loaves using these pans when I make bread. The bread comes out beautifully and never sticks. I cannot say enough about these pans- Love them.
I'm learning to bake and This thing works very well!
