ring shaped molds like tube pans and savarin have straight sides to make releasing delicate fine crumb cakes like angel food cake easier. Since the name "Bundt" is a trademark, similar pans are often sold as "fluted tube pans" or given other similar descriptive titles. The trademark holder Nordic Ware produces Bundt pans only in aluminum, but similar fluted pans are available in other materials. Despite the similar shape, a differs from contemporary Bundt-style cakes in that it follows a particular yeast-based recipe, with fruit and nuts, and is often deeper in shape and more decorative. Other yeasted, brioche-like cakes like babka, monkey bread can be baked in Bundt molds. Today, Bundt pans are also used to bake modernized cake batters and boxed mixes with baking powder, and can be used to mold gelatin salad, ice cream and even savory molded dishes like meatloaf. Rise to popularity The people credited with popularizing the Bundt cake are American businessman H. David Dalquist and his brother Mark S. Dalquist, who co-founded cookware company Nordic Ware based in St. Louis Park, Minnesota. In the late 1940s, Rose Joshua and Fannie Schanfield, friends and members of the Minneapolis Jewish-American Hadassah Society approached Dalquist asking if he could produce a modern version of a traditional cast iron dish. Dalquist and company engineer Don Nygren designed a cast aluminum version which Nordic Ware then made a small production run of in 1950. In order to successfully trademark the pans, a "t" was added to the word "Bund". A number of the original Bundt pans now reside in the Smithsonian collection. Initially, the Bundt pan sold so poorly that Nordic Ware considered discontinuing it. The product received a boost when it was mentioned in the New Good Housekeeping Cookbook in 1963, but did not gain real popularity until 1966, when a Bundt cake called the "Tunnel of Fudge", baked by Ella Helfrich, took second place at the annual Pillsbury Bake-Off and won its baker $5,000. The resulting publicity resulted in more than 200,000 requests to Pillsbury for Bundt pans and soon led to the Bundt pan surpassing the tin Jell-O mold as the most-sold pan in the United States. In the 1970s Pillsbury licensed the name Bundt from Nordic Ware and for a while sold a range of Bundt cake mixes. To date more than 60 million Bundt pans have been sold by Nordic Ware across North
