This disappeared from the Internet after I wrote Awesome Thanksgiving Science last year so I found an archive version before it disappears for good.

Here is a list of all the plants that we ate this Thanksgiving dinner. We made our usual dinner for 10 people, family and guests. Below the plant list is a list of the dishes we made.  Corn appears in many items that may not be obvious, such as mashed potatoes. However, turkey and dairy products are made from animals fed almost entirely on corn. So any item containing dairy products is listed as containing corn. The total number of plants is 42, though a few are different varieties of the same species. Sugar is of two potential sources, sugar cane and beet sugar. It happens that all the sugar we have on hand is cane sugar. Sugar not labeled as cane sugar is generally beet sugar.

We’d be interested in any other plants that you might have eaten this Thanksgiving. Please add in comments, and tell us both what plant you used (don’t worry about the species name and family) and in what dish you used the plant.
