I am in serious love with this cookbook. It's called Jeni's Splendid Ice Creams at Home and although I've owned it for less than a week, I've already made three recipes from it.
While you will dirty quite a few dishes while making these recipes, the process is simple and pretty much fool proof. I had no difficulties whatsoever, and will be trying more flavors form the book in the future.
If you have a home ice cream maker, you really need to check out this book. I've tried a lot of different recipes, and none have resulted in ice cream this good. Heck, better than good -- awesome!
