Identifying foods can be a fun cooking trivia game. You could purchase a bunch of uncommon fruits or vegetables and have people at your party guess what they are. Try stumping people by seeing if they can guess loganberries, tree strawberries or black velvet apricots. You can find more uncommon foods at ethnic specialty stores or health food stores.
Another cooking trivia game that you could play with friends or family is fun facts about foods. Research some of your favorite foods, and develop questions about them. You can think of your own fun facts or visit a website such as 2020Site.org for tons of fun food facts. The questions could be true or false or multiple choice. An example of a fun fact question is:
True or False? Americans eat 200 pizza slices per second. The answer is false; it is 350 slices per second.
You could use the history of cooking and food as trivia questions. Foodtimeline.org can provide you ideas on making up cooking history questions. You and your guests could have a fun time answering questions and learning about pie or the history of hot dogs.
