Join Lee and Rick, co-authors of “The Great Minnesota Cookbook,” at the Mall of America’s Rotunda for the 20th anniversary of the Star Tribune’s cookie contest. The first 15 years of the contest are featured in the cookbook. There will be music and loads of cookies (the winners from this year) — and Lee and Rick. And look for the 5 featured finalists in the Dec. 1 Taste section of the Star Tribune.
