With warmer weather tickling the air, I'm ready to roll up my sleeves and dig into a little Spring cleaning. Sure, there are ovens to clean and counters to scrub, but one task I'm forcing myself to tackle this season is tidying up my pantry and spice rack and clearing out old and expired items. Today I've rounded up some guidelines on how long to keep basic pantry staples and how to tell when they're ready for the trash (or compost). While these time frames are a general rule of thumb, it's important to use your senses to detect what to keep and what to toss: if anything looks, smells, or tastes strange, it's probably best to get rid of it. So let's get a-cleaning!
