Limited-edition collection serves up a taste of Japanese autumn with deliciously clever details.
Mister Donut is celebrating the arrival of autumn with five doughnuts inspired by one of Japan’s favourite seasonal ingredients: sweet potatoes. Called “Satsumaimo Do”, this new collection features five varieties, each designed to capture the flavour and texture of Japanese sweet potatoes in a different way.
▼ “Satsumaimo Do” combines the Japanese word for sweet potato (“satsumaimo”) with “do” (short for “doughnut”).
Sweet potato doughnuts are a popular seasonal offering at Mister Donut, but this year they’ve been given a new shape and thicker dough to make them look and feel even more like sweet potatoes. The shape is designed to resemble three small sweet potatoes joined together, made with a dough that contains 1.3 percent sweet potato powder for a delicious flavour and a soft, fluffy mouthfeel.
▼ Satsumaimo Do Plain (183 yen [US$1.15] for takeout; 187 yen dine-in)
The simplest of the five, this doughnut lets the sweet potato dough take centre stage, so you can fully enjoy the flavour and soft texture.
▼ Satsumaimo Do Stone-Roasted Sweet Potato-style (194 yen takeout; 198 yen dine-in)
This three-lobed doughnut is coated in a glaze that makes it look like three Japanese stone-roasted sweet potatoes, complete with a roasted sweetness to mimic the distinctive flavour.
▼ Satsumaimo Do Melty Salted Butter (194 yen takeout; 198 yen dine-in)
A lightly salted butter sauce and iced sugar coating gives this doughnut a delectably soft, gooey texture that adds a savoury-sweet contrast to the dough.
▼ Satsumaimo Do Fragrant Creme Brulee (216 yen takeout; 220 yen dine-in)
This version is topped with a layer of rich egg-based cream and finished with a crispy brulee sheet, creating a fantastic combination of creamy, crunchy and soft textures.
▼ Satsumaimo Do Rich Sweet Potato (216 yen takeout; 198 yen dine-in)
This beauty is filled with a rich sweet potato filling containing fresh cream, then baked in the oven to give the top a fragrant, roasted finish.
The Satsumaimo Do collection will be available at Mister Donut stores across Japan from 2 September, while stocks last.
