Burnt on food on enameled cast iron
Well, yesterday was my first time cooking in my new Staub enameled cast iron French/Dutch oven. I'm not sure if I did it right or not, but now I have a problem. I sauteed mushrooms and onions (now I'm assuming I should've removed them and added the meat), but I didn't. I added the meat and liquids and let it simmer for about an hour and a half. Well on the bottom I had burnt on food and was able to get most of it off after soaking the pot overnight and scrubbing really hard with a sponge, but there are still dark spots. Is there any way of getting rid of them. It's a good thing Staub used black matte enamel, but they are still visible and I'd really like to get them off. Also, how do I prevent this from happening again? Thank you so much for all the help.
