japanese sweet potatoes


I want to tell you about my new favorite food: The Japanese Sweet Potato.

Trader Joe's sells a 3lb bag of Japanese Sweet Potatoes for $3.99 here in Seattle. I decided to bake them whole, in the skin, and then planned to mash them with spices and butter after they were cooked. Turned out that they are so sweet and flavorful that I didn't even add salt! You can, of course, but I think you'll be as shocked as I was at the intense flavor that you may just want to eat them plain, like I do.

Heat your oven to 400F, scrub the outside of the potatoes, poke a few holes in them, and cook them on a pan for 30-60 minutes, depending on size. Let them cool a bit, peel them or slice them with a sharp knife (the skin gets dry but the inside is nice and soft) and eat them up! You can eat the skin, and many people think it's very important do do so, but I find the skin more enjoyable when I steam them vs. baking them. But I think that the flavor of the flesh is better when baked... so try both and see which one you prefer. They come out SO sticky sweet, truly as sweet as a dessert.

This is easy, cheap, nutritious, and downright delicious. Below are some facts about the background and nutrition content of these yummy tubers.

Enjoy!
