What are four basic preservatives you should keep on hand for storing foods?

We took it easy on you with this one. While alcohol is indeed a preservative, you might end up a bit preserved yourself with these ingredients for a Waldorf Cocktail, a Margarita, and a Hemingway daiquiri. The correct answer is salt, which reduces water content; sugar; oil, which essentially smothers bacteria; and vinegar, which creates a hostile environment for them.
