I accidentally bought a couple of Japanese sweet potatoes last week, along with the usual garnet yams, with sweet potato fries in mind. You know the Japanese ones – they are light yellow on the inside, darker purple on the outside and most commonly found breaded with tempura alongside sushi.
Of course I threw them into the mix, assuming it couldn’t hurt. It didn’t. In fact, I discovered that Japanese sweet potatoes are perfect for this preparation. Because of their higher starch content, they hold up better than regular sweet potatoes/yams (this reminds me to again research the difference between the two) and have a stronger resemblance to thick-cut french fries. They are also a bit less sweet, which I prefer.
Give it a try! General directions for sweet potato fries are found here. Once they are tossed in olive/peanut/safflower/grapeseed oil, salt and pepper, a quick 15-20 roast minute roast in a 425° oven is all it takes. End result? Happy, goofy kids:
