Why do sausages curve? Would they be straight if we didn't curl them while making? Is it inherit in the curve of the casings? If you were going to put a brat on a hotdog bun wouldn't it be better straight? Nearly everything I see is curved. Maybe we should curve the buns? We finally got the buns and the hotdogs to even out in the packaging. Why get curved buns? Inquiring minds want to know!
