The book offers a lot of helpful hints when making soup and a good selection of recipes.
I like that the author explains the difference between a stock and a broth which many books do not.
While I understand that recipes are variable and people change them to their liking - perfectly fine - there are a few errors. Cioppino is from San Francisco, not from Italy. Cooking times and amounts on some recipes are not correct, especially in bean soups it is vital to precook the beans before adding the rest of the ingredients or they will stay hard.
The key to a finished stock is that the gelatinous covering on the bones has dissolved in the soup which is a better gauge than when it tastes right.
I find that the variations on gumbos, lentil soups, tomato soups and a few others could have been described as variations of the master recipe rather than 6 gumbo recipes over 12 pages, etc.
A few other variations on recipes appear incorrect rather then just a variation.
All and all it is a pretty good book with many great recipes and lots of helpful hints.
