This book has some good basic information on the subject, but does not give enough depth or detail of each subject area to make it well worth buying. It's very basic, so I'm sorry I bought it. I'll go back and get something more detailed when I've had a chance to use this, as it's useless sitting around being passed from one person to another.
Bad review

This is an excellent product when you use in the oven. It makes it possible to cook casseroles and other dishes that take a long time to bake. And my favorite baked bean recipe turns out even more delicious using this pan. I put some water in each cup just before adding baking soda, which eliminates clumping, and then add my batter. It bakes up perfectly all around - no big globs of liquid left over. The pan heats evenly also, without getting hot spots anywhere.
Good Review

i thought this would last forever considering it's only $7 for two dollars of plastic, but within ONE WEEK both tabs were broken rendering them completely useless.
