Don’t wait for spring cleaning: January is a good month to go through cupboards for about-to-expire foods and impulse purchases you never got around to eating. Also check your cooking oils: They go rancid. If they don’t pass the sniff test (oil that has turned smells musty and old), toss them. If you don’t trust your nose, take a small taste). When you replace the oils, use a wine preservative spray to prolong the life of the more expensive ones. Click here for a preservative spray. And the best tip of all: Don’t buy more oil than you can reasonably use within 6 months.
