Veteran food-writer Brody has written a pleasant book filled with recipes for rich, tasty treats. She aptly calls the featured foods ``indulgences,'' and so they are by virtue of being rare, or difficult to get, or expensive, or all three. The rare category includes such as fraises de bois and mascarpone; the expensive, lobster and white truffles. Depending upon where you live, the difficult to get might include crayfish, or fresh figs. The recipes we tried, such as Jalapeno Surprise (made with peanut butter), were sometimes odd, but good. Recommended where there is demand for the exotic. Johanna Ezell, Mont Alto Campus. Lib., Pennsylvania State Univ.
