When it comes to the food college students consume, your thoughts may immediately go to instant ramen or a number of unhealthy snacks. But, during Japan’s economic recession in 1927, college students at Tokyo University were making do with a simple, flavorful, fried and glazed sweet potato dish called daigakuimo.

The name daigakuimo literally translates to “college potato” as the dish was a hit amongst the college crowd, according to the Nihon Imorui Kenkyu Kai, an association dedicated to potato research. The dish doesn’t require many ingredients but boasts an exceptionally rich flavor thanks to the soy sauce, sugar, and mirin (sweet cooking rice wine), and other ingredients.

Although it may have started as a lifeline for hungry students, daigakuimo’s popularity as a beloved side dish and healthy snack has transcended age groups over the course of history.

Today, you’ll find daigakuimo in the deli section of your local Japanese supermarket, but the recipe is easy enough to make at home, whether you’re a college student or not. So, give it a try!

*The above info is based on a recipe provided by Cookpad, a website dedicated to recipes.

*I set the microwave at 600W for this recipe.

*Once the food is ready and plated, make sure to add water to the pot/pan to boil. This will help remove excess sauce and prevent it from sticking to the surface of your pot/pan. Then, wash immediately.
