I spotted Japanese Sweet potatoes recently in a grocery store. Japanese sweet potatoes are called “satsuma-imo“. I had heard of them, but had never seen them.. They are a deep red/purple color on the outside and white on the inside. These were larger than what I expected. I decided to try some, not sure what I was going to do with them. After I boiled them I almost didn’t want to make the pie, they were so tasty.
Japanese vs. American Sweet Potatoes
Japanese sweet potatoes are sweeter than varieties found in the U.S. and have a rich, nutty flavor. I tried one with a little butter and sugar sprinkled on top and it was delicious. I decided to try them in the recipe I use for Sweet Potato Pie that I usually make around the holidays. The potatoes have a white flesh that turns yellowish when cooked, and they they do turn dark if left standing,
Adding just a few drops of food coloring can make the pie appealing.
The Japanese Sweet Potato Pie doesn’t need a crust if you don’t want one. I make it both ways. I like it without a crust and my husband likes it with a crust. My family loves it either way.
