I know a lot of couples out there are opting to cut their registries way down in favor of the cash (yea, we hear ya!)... but trust me when I say if there is just one thing left standing on your list it has to be this book! Justin and I got ours last year at our engagement party and we use it ALL the time. It's all about learning to cook together and taking the time to really enjoy each other. It covers all the basics to help get you started and has some incredible recipes...our favorite is the baguette french toast (p.48). yum!
