Your Photos: The Perfect Pair

We're celebrating Lamb Lovers' Month with the American Lamb Board and finding the most Valentine's Day-appropriate foods.

Human relationships can be unpredictable. Maybe you're not spending this Valentine's Day with the same person you spent last Valentine's Day with. And if you are, maybe that person has since dyed her hair or grown his beard.

Even if the face across the table is not the same, the food on it is most likely made of the same flavor pairings and ingredient couples. From salt and pepper and lemon and lime to cheese and pepperoni and lamb and mint, these food power couples have proven their stability throughout history.

So take a look at these perfect pairings -- you might even learn a lesson or two about your own relationship:
