Olive Oil
Baking. Cooking. No matter what the dish, olive oil can be a big part in making it come together. A healthier alternative to vegetable oil or canola oil, this is something that has become an essential item. Like many items on this list, it can hold well for very long periods of time, so buying in bulk won’t run the risk of seeing money poured down the drain. Consider stocking up on olive oil instead of buying a small, relatively expensive bottle every now and again.
