I have a lot of cookbooks and magazines that I use as a resource for recipes. Frankly, they're probably the most organized thing in my house! Organization is not something that gives me thrills, but there is something satisfying about needing a recipe and having it right at my fingertips.
I've been a subscriber to Taste of Home, Simple & Delicious, Healthy Cooking, and Southern Living off and on for pretty much my whole married life so I have a few magazines lying around. I've organized them by magazine type and date of issue on a shelf in my kitchen.
The good part about that is that I have a notebook that lists everything on the shelf. Under each publication's heading is a list of recipes I want to try that can be found within the pages, including which page number they are on.
On the unlined side of the card, I list out all the ingredients I need to purchase for the recipes I'm going to make that week. I don't bother writing things like milk and eggs down on my list because I buy them every week anyway. I double-check ingredients to make certain I have enough of everything, too. Something like vanilla extract is easy to run out of because I don't use it as often and I'm forgetful! The index card works well because I have the list of recipes on one side, too. If I can't find an item on my list, or it's more expensive than I expected, I can see at a glance what I needed the item for and whether a substitute will work just as well.
That's basically the process I go through each week to make out my list. I ask everyone in the family what they'd like to eat that week, though if I took their suggestions every time, we'd have spaghetti, hamburgers, fondue, sloppy joes and turkey sandwiches every single week. Nice.
