Query: You Will Learn Basic Crockpot Skills

Hoffman's recipes sound delicious, but in fact are often flavorless. If you use her recipes, you WILL learn slow cooking tecniques (stacking meat in the pot, thickening sauces, etc). But after 7 years of using this book, my notes on the recipes have a continual refrain: "Needs more pizzaz"; "Add vegetables"; "Flavors need more depth".
