As a young adult I lived where white sweet potatoes were prolific. When we raked and burned fall leaves, we'd throw a few in the fire, and eat them like candy as we worked. Yum.
I personally prefer baked sweet potatoes to baked white potatoes, and usually put a bushel in my root cellar every fall. I also use them in a variety of other ways but baking is easiest when cooking just for one. Next spring I plan to start growing my own if I can get slips in a timely fashion.
A couple of years back I found a hill of white sweet potatoes in my patch. Before this I did not know they existed. The nursery must have mixed it up with the rest of the dark orange. . My parents 80-85 years olds, favorite thing in the fall is me bringing in the sweet potatoes to them. I brought in the whites one to them and I was told flat out that they cared nothing for white sweet potatoes. So they were familiar with them, and for some reason they did not like them. I could not really tell a differences in the taste (I think I couldn't anyway) except they were not smooth, or uniform in shape or as big as the regular sweet potatoes. They also did not store as well. I think that is why my parents turned their noses up to the whites.
I still have sweet potatoes from this fall. It was a very good year for them this year. The best season I have ever had. I have given big Wal Mart shopping bags full to my cousins visiting out of Ohio, several neighbors, my parents of course, plus I have frozen 50 quarts and canned 60 quarts, and I still have plenty keeping good down in the basement. I feel like I have struck gold.
