What did Mrs. Claus (Bella Yellig) cook for Christmas Dinner? Santa Claus Museum founder (and Holiday World matriarch) Pat Koch shares her mother's recipes (along with her own) in this new cookbook. The Santa Claus Museum Cookbook is packed with nearly 500 old family recipes from families throughout Santa Claus and the surrounding area. There are also recipes from current and former employees of Holiday World & Splashin' Safari, Santa Claus Museum board members and volunteers, friends from other amusement parks around the country, and coaster-enthusiast friends.
