The origin of this name is often attributed to the dish’s popularity among university students in the early 20th century. As sweet potatoes were a relatively inexpensive and accessible ingredient, students would often prepare daigaku imo as a quick and affordable meal.

Key Ingredients and Their Significance
Daigaku imo, a delightful Japanese dessert, relies on a handful of essential ingredients, each contributing to its distinct flavor and texture.
The foundation of the dish is high-quality sweet potatoes, carefully selected for their natural sweetness and firm texture. These potatoes, when deep-fried, achieve a crispy exterior while maintaining a soft and fluffy interior.
Sweet Potatoes
- Varieties: Different varieties of sweet potatoes are used, each with unique characteristics. Beni-haruka, a Japanese variety, is popular for its vibrant orange flesh and balanced sweetness. Satsuma-imo, another Japanese variety, has a yellow flesh and a slightly nutty flavor.
- Selection: Choosing the right sweet potatoes is crucial. Look for firm and smooth potatoes, free from blemishes or cuts. A deep orange color often indicates a higher sugar content, resulting in a more flavorful daigaku imo.
- Preparation: The sweet potatoes are peeled and cut into bite-sized pieces before being deep-fried. This allows for even cooking and ensures a crispy exterior.
Sugar Syrup
- Ingredients: The sugar syrup is a simple mixture of sugar, water, and mirin, a sweet Japanese rice wine. The mirin adds a subtle umami flavor to the syrup, enhancing the overall taste of the dish.
- Preparation: The sugar and water are brought to a boil until the sugar dissolves completely. The mirin is then added, and the mixture is allowed to cool slightly before being poured over the fried sweet potatoes.
Toasted Sesame Seeds
- Flavor and Texture: Toasted sesame seeds add a nutty flavor and a delightful textural contrast to the soft sweet potatoes. They are sprinkled on top of the dish just before serving.
- Preparation: Sesame seeds are toasted in a pan over medium heat until they become fragrant and slightly browned. This process enhances their flavor and makes them more aromatic.
Step-by-Step Preparation Guide
Preparing daigaku imo involves careful preparation of sweet potatoes, creation of a sweet and savory sauce, combining the ingredients, and baking or frying the daigaku imo.
Preparing the Sweet Potatoes
To prepare the sweet potatoes, start by thoroughly washing and scrubbing them to remove any dirt or impurities. Peel the sweet potatoes using a sharp knife or vegetable peeler. Cut the peeled sweet potatoes into bite-sized pieces, typically 1-2 inches in size.
Cutting the sweet potatoes into uniform pieces ensures even cooking and helps them absorb the sauce more evenly.
Creating the Sweet and Savory Sauce
In a separate bowl, prepare the sweet and savory sauce that will coat the sweet potatoes. The sauce typically consists of soy sauce, mirin, sake, sugar, and grated ginger. Mix these ingredients in a bowl until the sugar has dissolved.
Adjust the quantities of each ingredient to achieve the desired balance of sweet and savory flavors.
Combining the Sweet Potatoes and Sauce
In a large bowl, combine the prepared sweet potato pieces and the sweet and savory sauce. Toss the sweet potatoes gently to ensure they are evenly coated with the sauce. Allow the sweet potatoes to marinate in the sauce for at least 30 minutes, allowing the flavors to meld and penetrate the sweet potatoes.
Baking or Frying the Daigaku Imo
There are two primary methods for cooking daigaku imo: baking and frying. For baking, preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Spread the marinated sweet potato pieces in a single layer on a baking sheet and bake for 20-25 minutes, or until they are tender and slightly browned.
For frying, heat a large skillet or deep fryer with enough oil to submerge the sweet potatoes. Fry the marinated sweet potatoes in batches until they are golden brown and crispy. Drain the fried daigaku imo on paper towels to remove excess oil.
