After you spend a while in the kitchen, you start to develop a personal repertoire of recipes and tips: your custom variation on classic pasta primavera, that delicious cocktail you invented by accident, the number of teaspoons in a packet of yeast (2 1/4). You could write all these down on paper or type them up in a Word document, sure, but good luck tracking them down later!
That's where this super-smart tip from The Kitchn comes in: use a Moleskine addressbook to alphabetically sort your recipes, references, and notes! The blank pages and A-Z tabs aren't just for phone numbers -- you'll be able to track down your favorite recipes at a glance. And as The Kitchn points out, the 4" x 6" size "makes it easy to carry along when you are staying at a vacation house or visiting family for the holidays."
