Sweet Potato Smackdown!

I've been wanting to discus the venerable sweet potato for quite a while. Having read Chilies to Chocolate: Food the Americas Gave to the World and History of Food I've been curious about the confusion surrounding sweet potatoes. I've also wanted to learn a bit more about them and see if there were difference between the available varieties.

In the last 100 years there's been a trend to shrink the genetic biodiversity of our food resulting in less choice. After growing tomatoes and many herbs I have become well aware that you grow food so you can have the right food, not necessarily to save money. It is cheaper to grow your own but if you factor in your labor a garden you probably costs you twice as much as just buying the food but the advantage is better quality and more choice. There are paste tomatoes, slicing tomatoes and sauce tomatoes depending on your needs. There are many different varieties of mint (chocolate mint is very nice), basil and other herbs. You can grow pumpkins for Halloween and pumpkins to eat (not the same thing, see my previous articles on pumpkins). However, we're nearing a disaster of epidemic proportions. Not only are we engineering seeds that can't produce more seeds and then patenting them so other people can't grow food without paying for the seeds but the plants can't survive without us making them subject to our commercial interests. There are seed banks trying to combat this but that will only allow us to plant these various crops, it won't give anyone the incentive to do it.

We are narrowing our biodiversity for commercial profit. It's just easier to grow and ship two types of tomatoes than 10. Likewise it's easier to provide one type of basil, one type of mint, one type of sage etc... Another reason may be that people are just further removed from their food than they once were so we don't pay attention to the different types of foods we have available. If you've never studied sweet potatoes you may think there's only one type – labeled Sweet Potatoes in the store. In fact there are over 6,500 varieties of sweet potatoes. Obviously we can't try them all so I focused on the three varieties commonly available in super markets – Beauregard, Garnet and Jersey. I've seen the Jewel variety in stores too on occasion but they weren't available for this comparison so I may do a follow up when I can find some.

I tested three varieties cooked in 4 different ways and noted the difference. Before you skip the rest of the article because you think they're all the same you might want to reconsider. Read the article after the jump.
