I have a lot of books about cocktails, but this one is a basic I turn to again and again. Gary Regan (“Gaz”) talks about spirits, their background, history and uses brand names. He draws a fascinating chart of cocktails by ingredient and combination — duos, trios — and tells you when an old recipe needs personal “tweaking.” If you buy only one book about booze, make it this one.
