While pigs in a blanket may seem intrinsically American, just about every culture has something that compares. In England, puff pastry is wrapped around fresh sausage to make what are known simply as "sausage rolls." (The British usage of "pigs in a blanket" refers to hot dogs wrapped in bacon, which the Danish translate verbatim as pølse i svøb and sell from kiosks on the street, bun on the side.) In Hong Kong, fluffy white Cantonese yeast dough swaddles frankfurters that are baked and dotted with mayonnaise to yield yit gau baau, or "hot dog buns." Despite Rombauer's invitation to improvise, in the United States, we are wont to open tins of Vienna sausages, smash open cardboard tubes of premade Pillsbury dough, and make Crescent Dogs, a party sensation since they and the Poppin' Fresh dough boy debuted in 1965.
