Dried beans are much cheaper than canned beans, and the finished product tastes better, but if you use chickpeas frequently as a component of stews or soups, it might not be an effective use of time or an important money-saver to start with dry chickpeas every time.
I purchase by the case cans of those beans I use frequently. For dishes in which beans play a pivotal role, I use dried beans, especially white beans, cranberry beans and flageolet beans. I think that baked beans, made well and with the addition of some bread, is a pretty perfect winter supper, but you may not agree. Every cook has different priorities.
At the same time, I do love when chefs and other food writers include lists of pantry staples. I read them eagerly, hoping to stumble upon some new exciting ingredient. So I'll compromise. The following is a list of categories that may help you in evaluating and building up your pantry (and fridge, freezer and basement) staples, along with examples from my own kitchen.
The most important qualities of a well-stocked pantry are having items you use often in large quantities and having a broad enough variety that they can be pulled together into a meal. Also, so you don't get bored, try to keep around a couple of pantry splurges that will keep you excited about the contents of your cupboard.
Don't, however, buy items in such large quantities that they'll get old before you get through them. Depending upon how well you store it, Jasmine rice may lose its fragrant qualities after a few months. Onions and potatoes will start to sprout.
Many people bristle at throwing out spices every year, and, frankly, it's not the most useful rule of thumb. Instead, buy whole spices if possible and grind them in a coffee grinder (ideally dedicated for that task) or a mortar and pestle. Or, use the sniff test. If it doesn't smell like much, it won't taste like much.
