How to pick the right Japanese sweet potatoes for air frying
Japanese sweet potatoes are distinct from other sweet potatoes in terms of colour, texture, and flavour. The most common varieties are satsuma-imo or murasaki. The former is commonly labelled as "Japanese sweet potato" in US grocery stores. The latter is a favourite for air-frying.
The Japanese variety is usually magenta or auburn on the outside and pale, almost white, on the inside. They are starchier and denser than other sweet potatoes, resulting in a unique flavour and eating experience. As they cook, the inside turns golden yellow, and the texture becomes light, fluffy, and creamy.
When selecting Japanese sweet potatoes for air frying, look for medium-sized ones (approximately 4–5 inches in length) with purple or magenta skin. They can be found at local Japanese, Taiwanese, Chinese, and Korean grocery stores, as well as large grocery store chains such as Ralphs and Whole Foods.
To prepare Japanese sweet potato fries, start by cutting the ends off the potatoes. Then, cut each potato in half lengthwise, and then cut each half into four fries. It is important to ensure that the fries are of equal size so that they cook evenly.
Next, toss the cut potatoes in a bowl with sesame oil and furikake seasoning. Use your hands to thoroughly coat the potatoes with the oil and seasoning. Place the potatoes in a single layer in the air fryer. If your air fryer is small, you may need to cook the potatoes in batches.
Air fry the potatoes at 350 degrees Fahrenheit for 15 to 20 minutes, or until crispy and cooked through. If desired, sprinkle with extra furikake seasoning or sea salt after cooking.

To cut Japanese sweet potatoes for air frying, start by washing the sweet potatoes thoroughly and patting them dry with a paper towel or a clean kitchen towel to remove any excess moisture. Next, use a sharp knife to cut the sweet potatoes into evenly sized pieces. You can cut them into cubes, slices, wedges, or fries, depending on your preference.
