Query: Disappointing

I like the idea of this book - basic recipes for muffins with variations on each theme. I liked the helpful tips, and the recipes for toppings in the back of the book. But I have tried a fair number of recipes, and each was disappointing. The muffins lacked flavor and spice, and were heavy on the flour. None of the recipes were "keepers", according to my family. I'm puzzled by reviews stating a cookbook is "an excellent treatment of the subject", apparently without trying the recipes and tasting the results. You have to cook from a cookbook to know if it is any good! I'd recommend checking this one out of the library for a trial, if you have an interest in the book.
