10. Thomas' English Muffins
On the surface, it doesn't seem that hard to reverse-engineer Thomas' recipe; after all, the famous nooks and crannies are basically the product of flour, water, and yeast, with assorted other well-known ingredients thrown in for flavor and texture. Yet the company takes its trade secrets very seriously, and recently went to court to protect them. In January 2010, Chris Botticella -- one of only seven Thomas' executives who knows the exact combination of dough, humidity and baking technique necessary to reproduce the muffins -- left Thomas' for a new job at competitor (and Wonder Bread manufacturer) Hostess. The case is currently on appeal, and Botticella has been barred from accepting his new job until the case is settled.
