well, the book is called sauces, classical anbd contemporary. It is the best book I have ever seen on this particular subject. the guy goes far into the depth of sauce making and definition, not to mention the recipes, and it is quite a good read as far as keeping you interested goes, I highly reccomend this to anyone willing to look at it. Your public library should have it(and youd personal library should too

), if your city is big enough...they did, after all, in peterborough.
