Ingredients

For the Potato Balls

• 2 large potatoes (about 1 lb), peeled
• 1/2 cup potato starch or cornstarch
• 1/4 tsp salt
• 1/4 tsp white pepper
• 1 tbsp vegetable oil

For the Sauce

• 2 tbsp soy sauce
• 1 tbsp rice vinegar
• 1 tsp sugar
• 1 tsp sesame oil
• 1 clove garlic, minced
• 1 tsp sesame seeds
• 1 green onion, chopped

Equipment Needed

• Large pot
• Colander
• Potato masher or fork
• Mixing bowl
• Measuring spoons
• Small bowl
• Non-stick skillet or frying pan
• Spatula

Instructions

Step 1: Boil and Mash the Potatoes

Peel 2 large potatoes (about 1 lb) and cut them into uniform chunks for even cooking. Place them in a large pot and cover with cold water by 1 inch. Bring to a boil over high heat, then reduce to medium and cook for 15-18 minutes until fork-tender. Drain in a colander and let them steam dry for 2 minutes to remove excess moisture. Return to the pot and mash thoroughly with a potato masher or fork until completely smooth with no lumps. Let cool for 5 minutes so the starch doesn't activate too quickly.

Step 2: Form the Dough

To the mashed potatoes, add 1/2 cup potato starch (or cornstarch), 1/4 tsp salt, and 1/4 tsp white pepper. Mix with a spatula or your hands until a soft, cohesive dough forms. The dough should be slightly sticky but hold together when pressed. If it's too wet, add a little more starch (1 tsp at a time). If too dry, add a few drops of water. Avoid overmixing, as that can make the balls gummy.

Step 3: Shape the Potato Balls

Lightly dust your hands with potato starch to prevent sticking. Scoop about 1 tablespoon of dough and roll it between your palms into a smooth ball about 1 inch in diameter. Place on a plate. Repeat with the remaining dough. Once all are shaped, use your thumb to press a deep indent into the center of each ball, creating a fingerprint-like well. This helps the sauce pool inside. Ensure the balls are uniform in size for even cooking.

Step 4: Pan-Fry Until Golden

Heat 1 tbsp vegetable oil in a large non-stick skillet over medium heat. Carefully place the potato balls in a single layer, leaving space between them. Cook undisturbed for 3-4 minutes until the bottoms are deep golden brown and crispy. Flip using a spatula and cook the other side for another 3-4 minutes. The balls should be evenly browned and feel firm to the touch. Adjust heat if they brown too quickly. Transfer to a serving plate.

Step 5: Make the Sauce

In a small bowl, whisk together 2 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp sugar, 1 tsp sesame oil, and 1 minced garlic clove. Stir until the sugar dissolves. This sauce can be made ahead while the potato balls cook. Taste and adjust with a pinch more sugar if you prefer a sweeter profile.

Step 6: Assemble and Serve

Pour the sauce evenly over the hot potato balls, allowing it to seep into the indentations. Sprinkle with 1 tsp sesame seeds and chopped green onion from 1 stalk. Serve immediately while the balls are still warm and crispy. The sauce will soften the exterior slightly, creating a delightful contrast with the creamy interior.

Tips and Tricks

Use Starchy Potatoes

Russet or Yukon Gold potatoes work best because they mash into a fluffy, dry texture. Waxy potatoes like red or new potatoes contain more moisture and can make the dough sticky, requiring extra starch.

Don't Skip the Cooling Step

Let the mashed potatoes cool for a few minutes before adding starch. Hot potatoes can activate the starch too quickly, resulting in a gummy dough. Cooling also makes shaping easier.

Reheat for Crispiness

To reheat leftovers, place the potato balls on a baking sheet and warm in a 375°F oven for 5-7 minutes. Avoid microwaving, as it will make them soggy.

Recipe Variations

• Spicy Kick: Add 1/2 tsp gochugaru or chili flakes to the sauce.
• Herb-Infused: Mix 1 tbsp chopped parsley or dill into the potato dough.
• Cheesy Center: Press a small cube of mozzarella into the center of each ball before shaping.
• Gluten-Free: Use tamari instead of soy sauce and ensure potato starch is certified gluten-free.

Frequently Asked Questions

Here are answers to common questions about making fingerprint potato balls, so you can achieve perfect results every time.

Can I use sweet potatoes instead?

Yes, sweet potatoes work but they have more moisture and sugar. You may need to add an extra tablespoon of starch and reduce cooking time slightly to prevent burning. The flavor will be sweeter and less savory.

How do I prevent the balls from falling apart?

Ensure the mashed potatoes are smooth and well-mixed with the starch. If the dough crumbles, add a teaspoon of water. If too sticky, add more starch. Also, handle the balls gently when flipping.

Can I bake these instead of frying?

Yes, arrange the balls on a parchment-lined baking sheet, brush with oil, and bake at 400°F for 15-18 minutes, flipping halfway. They will be less crispy but still tasty.

What if I don't have potato starch?

Cornstarch is an excellent substitute and yields a similar texture. Arrowroot powder also works. Avoid using flour, as it will make the balls dense.
