OK, pancake-challenged girls...mine always turn out just fine. I think it's because I bought one of those Pampered Chef non-stick skillets. Turn on your burner, put the pan on it. Heat the pan at medium. When a drop or two of water dances on your pan, the heat is right.
Spray with no-stick spray, and then pour on your batter. DO NOT turn the pancake until there are bubbles on the top of the batter that are popping open.
The second side takes less time than the first.
For you rice-krispy challenged girls, don't cook them when the humidity is high. They won't set. Other than that, I can't help you.
For your chicken challenges, get a meat thermometer. They don't cost much. Cook your poultry to an internal temperature of about 170 degrees. I turns out perfectly every time!
Pooh, with your gravy, are you introducing heat to your thickening agent before putting it into the pan? If you're using flour, put a spoon or two of hot liquid into your flour mixture before pouring it into the cooking pan.
Meringues won't work if your mixing bowl has the slightest amount of oil or grease in it.
I make fettuccini alfredo often. What I've found to be the secrets: Lots of fresh parmesan cheese, freshly grated. Don't buy the stuff in the can or the pre-grated stuff in the bag. Don't rinse the fettuccini after cooking it.
I use an egg yolk, an 8 oz. carton of heavy cream, and then parmesan for the proper consistency. Heat the cream and egg yolk, pour in the fettucini, and then after it's had a few minutes of bubbling, add the cheese. Season with nutmeg and a little salt. YUM.
French toast, like pancakes, needs a good non-stick pan with medium heat and non-stick spray.
Potatos--well, I'm not so good at those. I can't help you there.
Brownies seem to always turn out right for me if I cook them in a Pampered Chef stone.
LOL, I sound like a Pampered Chef ad. I don't mean to!
