The OC's stands for "the original cooks", including Becky Quinn, Gina Silvers, and Ida Perez. They received the cookbook from the Traveler in the 1960's while lost on a school field trip. As they were the protectors, they created and used many recipes together, and tried to make Chuck forget magic together as well. Over time, the book led to the ending of their friendship, but they do reconcile many years later. The OC's didn't remember magic after Jill/Caroline cursed them to forget magic until Hannah, Kelly, Darbie and Piper used a quiche to wake them all up to remember magic.
