The awesomeness of sour cream, onion and potato together can't be measured by modern science. We've decided it's simply a flavor combination nature intended and man perfected. We don't question it. We'll just keep making 'em, as long as you keep nomming 'em.
We didn't use just any cheese flavor in these crisps. We went with cheddar, the king of cheeses. So you could even say it's a royal flavor. It's so majestically good, you might not want to mention it to your lactose-intolerant friends.
