Complete Guide to Imo Fry | Complete Explanation of the History, How to Make, and Famous Restaurants of Tochigi Prefecture Sano City’s Local Cuisine
What is Imo Fry?
Imo Fry is a Tochigi Prefecture local dish made by cutting steamed potatoes into bite-sized pieces, skewering them, coating them with a batter made of wheat flour and breadcrumbs, deep-frying them in oil, and finishing with a special sauce. It is particularly enjoyed in the North Kanto region centered around Sano City, where locals eat it as a “soul food” on a daily basis.
Though seemingly a simple dish, it is characterized by a profound flavor combining the natural sweetness of steamed potatoes, their fluffy texture, crispy fried coating, and the exquisite match with locally-made special sauce. It is loved not only as a snack, but also as a side dish for dinner and as an accompaniment to alcohol.
Basic Structure of Imo Fry
The defining characteristic of imo fry is that raw potatoes are never fried; they are always steamed or boiled first before frying. This process brings out the natural sweetness of the potatoes and creates a fluffy texture.
The main ingredients are as follows:
- Potatoes: Danshaku varieties and other fluffy types are the mainstream
- Batter: A light batter made with wheat flour and breadcrumbs
- Special Sauce: Based on local sauce maker sauces, each restaurant blends their own unique version
- Skewers: Easy to carry and perfect for eating on the go
The Deep Connection Between Tochigi Prefecture’s Sano City and Imo Fry
Why Sano City is the Holy Land of Imo Fry
Tochigi Prefecture’s Sano City is known as the birthplace of imo fry. Within Sano City, there are dozens of restaurants serving imo fry, each competing with their own unique flavors.
For Sano City residents, imo fry is such an everyday food that many citizens once thought it was “a food found everywhere throughout Japan.” However, in reality, it is a unique local food found only in limited areas of North Kanto centered around Sano City.
Tochigi Prefecture’s Sauce Culture Zone
Tochigi Prefecture, particularly the Ryomo region including Sano and Ashikaga cities, is known as one of Japan’s premier sauce culture zones. Multiple long-established sauce makers have continued since the Meiji era, and the number of sauce manufacturers in Tochigi Prefecture ranks third in the nation.
This rich sauce culture has nurtured imo fry as a local dish. Each restaurant uses sauce from local sauce makers as the base and blends their own special sauce, which becomes the deciding factor in the taste of imo fry.
The History and Birth Story of Imo Fry
The Flavor of Common People Beginning with Postwar Street Vendors
The history of imo fry traces back to after World War II. During the food shortage era following the war, street vendors in Sano City, Tochigi Prefecture are said to have begun selling it from pushcarts.
At the time, potatoes were a relatively easily obtainable ingredient. By steaming them, skewering them, coating them with simple batter, and frying them, they became an easy-to-eat, nutritious food that spread among the common people.
Connection with Candy Store Culture
From the 1950s through the 1960s, imo fry became established as a candy store menu item. Children would stop by candy stores on their way home from school and buy them as a cheap snack for about 10 yen per piece.
Imo fry from this era was smaller than it is today and had a more casual eating style. The sight of people munching on freshly fried imo fry in front of candy stores was a common scene in Sano City at that time.
Re-evaluation as B-Grade Gourmet Food
With the advent of a nationwide B-grade gourmet boom in the Heisei era, imo fry came to be re-evaluated as Sano’s local B-grade gourmet food. Centered around the Sano City Tourist Association, active PR activities were conducted to promote it as a regional specialty, and it became known to tourists.
Today, many tourists visiting Sano City come specifically for imo fry alongside Sano ramen.
How to Make Imo Fry | Complete Recipe Revealed
Basic Ingredients (Serves 4)
- Potatoes (Danshaku variety): 4-6 medium-sized potatoes
- Wheat flour: 100g
- Breadcrumbs: 150g
- Water: as needed
- Cooking oil: as needed
- Bamboo skewers: 8-12
- Worcestershire sauce: 4 tablespoons
- Medium-strength sauce: 2 tablespoons
- Mirin: 1 teaspoon
- Sugar: 1/2 teaspoon
Preparation Tips
1. Selecting Potatoes
Danshaku potatoes with a fluffy texture are ideal for imo fry. Starchy potatoes like Maygeen are not suitable for imo fry. It is better to choose potatoes that have been stored for some time and have increased in sweetness rather than new potatoes.
2. Steaming Tips
There are two methods: steaming potatoes after peeling, and steaming with the skin on and then peeling. Steaming with the skin on preserves the umami flavor better and enhances the fluffy texture.
Step-by-Step Instructions
Step 1: Steam the Potatoes
- Wash the potatoes well and steam them with the skin on in a steamer for 20-30 minutes
- Stop heating when a bamboo skewer passes through easily
- Once cooled slightly, peel and cut large pieces into eighths and smaller pieces into quarters
Step 2: Skewer
- Pierce the cut potatoes with bamboo skewers
- Aim for 2-3 pieces per skewer
- Leave a little of the skewer tip exposed for easier handling
Step 3: Apply Batter
- Dissolve wheat flour in water to make a slightly loose batter (slightly thicker than tempura batter)
- Dip the skewered potatoes into the batter
- Coat evenly with breadcrumbs
- Press lightly to firmly attach the breadcrumbs
Step 4: Deep Fry
- Heat the cooking oil to 170-180°C
- Gently place the skewered potatoes in the oil
- Fry for 2-3 minutes until the coating turns golden brown
- Remove and drain well
Step 5: Apply Special Sauce
- Mix Worcestershire sauce and medium-strength sauce together
- Add mirin and sugar for a milder flavor
- Generously coat the freshly fried imo fry
Variations for Home Cooking
Easy Version Using Microwave
If you don’t have a steamer, a microwave can be substituted:
- Peel the potatoes, cut into bite-sized pieces, and soak in water
- Arrange on a heat-resistant plate, cover with plastic wrap, and heat at 600W for 4-5 minutes
- Once a bamboo skewer passes through, proceed with the regular steps
Sauce Variations
- Sweet Sauce: Add honey to Worcestershire sauce
- Spicy Sauce: Add chili powder or Tabasco
- Mayonnaise Mix: Blend mayonnaise with sauce for a milder flavor
- Aonori Topping: Sprinkle seaweed powder after applying sauce
The Scientific Reason Why Imo Fry Tastes Good
The Sweetness Created by Steaming Potatoes
Steaming potatoes converts starch into sugar, increasing natural sweetness. Unlike french fries made from raw potatoes, imo fry maximizes the original umami flavor of potatoes through steaming.
The Exquisite Balance Between Batter and Sauce
Imo fry batter has an exquisite thickness between tempura and tonkatsu breading. This batter absorbs sauce appropriately while maintaining a crispy texture.
The sauce soaks into the batter and blends with the sweetness of the potatoes, creating a complex flavor. This balance is the greatest appeal of imo fry.
Taste Changes with Temperature
Piping hot freshly fried imo fry brings out the steam and aroma of sauce, creating the best flavor. On the other hand, slightly cooled imo fry allows the sauce to thoroughly blend with the batter, offering a different delightful taste.
