Preparation
Ingredients
| Ingredient | Quantity |
|---|---|
| Japanese sweet potatoes (satsumaimo) | 2 medium-sized |
| Vegetable oil (for frying) | As needed |
| Granulated sugar | 1/3 cup |
| Water | 2 tablespoons |
| Black sesame seeds (for garnish) | Optional |
| Salt | Pinch (optional) |
Steps to Prepare Daigaku Imo
- Wash and Prepare the Sweet Potatoes: Start by washing the sweet potatoes thoroughly under running water. Peel them if you prefer, then cut them into bite-sized pieces (about 3-4 cm thick).
- Soak the Pieces: Place the cut sweet potatoes in a bowl of water and let them soak for about 10 minutes. This helps to remove excess starch, which results in a crispier texture after frying.
- Drain and Dry: After soaking, drain the sweet potatoes and pat them dry with a kitchen towel. Make sure they are as dry as possible to ensure better frying results.
- Heat the Oil: In a deep frying pan or pot, heat enough vegetable oil to fully submerge the sweet potatoes. The temperature should reach about 170°C (340°F).
- Fry the Sweet Potatoes: Carefully add the sweet potato pieces to the hot oil in batches, making sure not to overcrowd the pan. Fry them for about 5-7 minutes or until they are golden brown and tender. Use a slotted spoon to remove them and place them on a paper towel to absorb excess oil.
- Prepare the Syrup: In a small saucepan, combine sugar and water. Heat it over low-medium heat, stirring until the sugar dissolves completely. Allow it to simmer until it thickens slightly, approximately 2-3 minutes.
- Coat the Sweet Potatoes: Once the sweet potatoes are fried, quickly toss them in the syrup mixture until they are evenly coated.
- Garnish (Optional): Transfer the coated sweet potatoes to a serving plate and sprinkle with black sesame seeds and a pinch of salt if desired. This adds an extra layer of flavor and a delightful crunch.
- Serve and Enjoy: Daigaku Imo is best enjoyed warm. Serve immediately and savor the sweet and crispy delight that embodies traditional Japanese flavors!
