🍠 WHAT ARE JAPANESE SWEET POTATOES?

There are several varieties of sweet potatoes, but you’re probably most familiar with the Beauregard variety, which is the most common cultivar in the U.S. We’ll use this orange-fleshed cultivar as a jumping off point to compare to the Japanese variety.

Color:

• Orange sweet potatoes are orange-brown on the outside. They are a vibrant orange color on the inside, which does not change when cooked.
• Japanese sweet potatoes have a characteristic red-purple hue on the outside. They are cream colored on the inside, which changes to a soft yellow when cooked.

Flavor

• Japanese sweet potatoes are sweeter compared to orange sweet potatoes and have a nutty flavor profile.

Texture

• Orange sweet potatoes have a higher moisture content in contrast to Japanese sweet potatoes.
• Japanese sweet potatoes are lower in moisture and higher in starch, similar to Russet potatoes. This combination yields a fluffier texture than orange sweet potatoes, which makes them wonderful for dry heat modes of cooking, such as baking or roasting.

🇸🇪 WHAT IS A HASSELBACK POTATO?

Have you Hasselback-ed?

The Hasselback potato hails from Sweden, where it’s known as Hasselbackspotatis. It takes its name from a Stockholm restaurant called Hasselbacken, which invented the dish.

Each potato is partially sliced into a row of thin slivers that remain attached at the base. The potato is then brushed with a fat, before being baked to perfection. The potato becomes crisp and crunchy on the outside and soft and creamy on the inside. The fillings and toppings pool down in the spaces between the slices, which makes for a flavor explosion with every bite.

Once you Hasselback, you’ll never go BACK!

📝 INGREDIENTS

• Japanese sweet potatoes: This low moisture, high starch potato is perfect for baking and roasting.
• Miso paste: Miso paste is made from fermented soybeans. Miso paste is earthy, rich and salty-sweet. The longer the paste ferments, the darker in color and more complex in flavor it becomes. We like to use white miso paste, the lightest color, to make our miso butter. White miso paste is the mildest in flavor, and does not overpower the flavor or sweetness of our Japanese sweet potato. You can find miso paste at most grocery stores. We’ve found it in stores such as Kroger, Sprouts and Whole Foods. Otherwise, you’ll definitely be able to find it in your local Asian grocery store.
• Vegan butter: Adds richness and a savoriness that balances sweetness of the miso paste and sweet potato.
• Vegan sour cream: adds tartness and creaminess.
• Furikake: Furikake is a Japanese seasoning mixture that contains sesame seeds, dried seaweed, salt and sugar. It adds a savory, nutty, seafood-y flavor. There are many seasoning mixtures that contain fish or egg, so check the ingredient list to ensure it is vegan. Note: Make sure to avoid mixtures including ingredients such as bonito flakes, katsuobushi and okaka, which are derived from fish and are not vegan. You can find furikake at your local Asian grocery store or on Amazon.
• Green onions: Adds an element of freshness and a sharp, peppery onion flavor.

💡RECIPE TIPS

• Break out the chopsticks: Position the potato between two chopsticks to add stability and prevent you from slicing all the way through the potato.
• Use room temperature vegan butter: You want your compound butter with miso to be silky and evenly combined. To achieve this, bring your vegan butter up to room temperature. This will make it easier to cream it together with the miso paste. DO NOT microwave the butter. Microwaved butter will not bind with miso paste, and you’ll wind up with yucky, unappetizing clumps of miso paste.
• Whisk or fork it up: Use a whisk or fork to cream together your miso paste with room temp butter.
• Sharpen that knife: Japanese sweet potatoes are firm, so make sure to use a very sharp knife. You’ll want potato slices that are uniformly ⅛ inch to ensure even cooking. Leave the slices attached at the base of the potato; do not cut through the bottom ¼ inch of the potato.
• Cooking times may vary: An average medium-sized Japanese sweet potato will take 45 minutes to air fry. But the cook time may increase to as much as an hour, depending on the size of the potato. can go up to 60 minutes.
• Don’t have an air fryer? No problem. Bake the potatoes in a conventional oven at 400 degrees Fahrenheit for 55 to 70 minutes.
