It's The Sponge Dough In Your Buns

Puritan buns, yet. They're the secret behind several fine Southern Calif. burger chains. And we learn this now because the guy who developed Puritan's specially formulated 4-inch buns has passed to the great bakery in the sky.

"Not only are our hamburger buns absolutely delicious," Puritan's website says, "they are specially designed to stand up on the grill and will not fall apart when full of meat juices, dressings and condiments." It's a seven-hour process to make the buns, from sponge to final product.
