I'm sure we all remember the Periodic Table of Elements from chemistry studies in school. Courtesy of Epicurious, we learn that there are several other Periodic Tables, these ones related to food. The last two links, for beer types and storing produce, no longer work, so I looked those up and provided new ones. The tables are:
Periodic Table of Condiments
Periodic Table of Cupcakes
Periodic Table of Candy
Periodic Table of Beer Styles
Periodic Table of Storing Produce
Amazon carries periodic table posters too
Fun stuff, particularly for younger cooks who need entertainment.
