You may have noticed a curious thing when traveling. The store-brand eggs you buy in one state can look and taste different from the same brand of eggs you buy in another. The yolk might be a pale yellow in one region and a deep, rich orange in another. This is not your imagination. This difference is a direct result of the complex, regional nature of our food supply chain. Several key factors explain why the same brand of eggs can be a completely different product depending on where you buy them.
