Crispy Sweet Potato Balls

These little sweet potato sesame treats turn basic items into mouthwatering bites with crunchy outsides and tender, sweet middles. When you mix sticky rice flour with sweet potato, you get that amazing chewy bite, while the sesame coating adds a nutty taste that works perfectly with the natural sweetness inside.

I first tried these yummy treats at a Taiwan cooking workshop and have been making them for family get-togethers ever since. These days, my nieces always ask me to bring them to every holiday party as our family tradition.

Ingredients

• Sweet potato: Gives natural sweetness and lovely color
• Glutinous rice flour: Makes that signature chewy feel common in Asian sweets
• Sugar: Brings out the sweet potato taste without being too much
• Sesame seeds: Add that nutty flavor and create the crunchy outer layer
• Cooking oil: Needs to handle high heat for proper frying temps

Step-by-Step Instructions

Prepare the sweet potato:

First, poke your sweet potato multiple times with a fork before you bake it. This lets steam escape while it cooks, so your potato won't burst in the oven and will cook all the way through. Bake at 400°F for around 45 minutes until it's totally soft when you stick a knife in it.

Create the perfect dough:

After your sweet potato has cooled enough to touch, peel off the skin and mash the inside until it's completely smooth with no chunks left. The trick is to add your sticky rice flour bit by bit while mixing with a spatula first, then your hands. You want dough that feels soft and bendable but doesn't stick to your fingers.

Form uniform balls:

Split your dough into 12 equal pieces so they'll cook the same. Roll each piece between your hands with light pressure until they're perfectly round. Your warm hands will make the dough easier to shape.

Apply the sesame coating:

Mix sticky rice flour with water until smooth to make a thin paste. This helps the sesame seeds stick properly. Dip each ball in this paste, then put it in sesame seeds and roll it around gently to cover completely. Lightly press afterward to make sure the seeds stay put.

Master the frying technique:

The secret to great sesame balls is getting the heat just right. Start at 250°F then keep medium heat the whole time you're cooking. You'll know they're done when the dough showing between seeds turns bright orange, which means the inside is fully cooked while the outside is perfectly crispy.

The sweet potato really shines in this dish. My grandma used to grow purple sweet potatoes in her backyard that made the prettiest light purple sesame balls. I still cherish those childhood moments of helping her dig up potatoes and turn them into these treats—they're some of my favorite cooking memories.

Storage and Reheating

These sweet potato sesame balls taste best fresh, but you can keep them in an airtight container at room temp for up to 2 days. To make them crispy again, warm them in a 350°F oven for about 10 minutes. Don't use the microwave or they'll get soggy. If you need to store them longer, you can freeze them. Put cooled balls on a baking sheet until they're completely frozen, then move them to freezer bags for up to 1 month. When you're ready to eat them, heat from frozen in a 350°F oven for 15 minutes.

Troubleshooting Common Issues

The biggest problem folks run into is getting the dough just right. If your dough feels too sticky, just add more sticky rice flour a spoonful at a time. If it seems too dry and breaks when you roll it, mix in a little water or more mashed sweet potato. When it comes to frying problems, oil temperature matters a lot. If your balls turn brown too fast, your oil's too hot. If they soak up too much oil and get greasy, your oil's not hot enough. Always use a thermometer for best results.

Cultural Significance

Sweet potato sesame balls are a twist on traditional Chinese jian dui, which usually have sweet bean paste inside. This version shows how recipes change across cultures while keeping their core idea. In many East Asian countries, round foods stand for unity and completeness, which is why these treats show up at family gatherings and celebrations. The golden color they turn when fried also stands for wealth and good luck, explaining why they're so popular during Lunar New Year parties.

These sweet potato sesame balls aren't hard to make and they'll wow everyone, bringing both flavor and tradition to your meals.

Recipe Q&A

→ Can I try a different type of sweet potato?

Absolutely! Feel free to use orange, purple, or white sweet potatoes. Each type will bring a unique color and flavor to the balls.

→ Why do the balls sometimes pop open while frying?

Bursting happens when the oil gets too hot. Keep the temp around 125°C/250°F, frying at a medium heat. Be sure the dough is mixed well and the sesame seeds are pressed on firmly.

→ Can I prep these ahead of time?

Yes, shape the dough into balls and store them in the fridge for up to a day. They'll fry best fresh but can also be reheated in the oven for crispness.

→ Would an air fryer work for these?

If you’re avoiding deep frying, air fry at 180°C/350°F for 10-12 minutes. Spray oil lightly beforehand. The texture may differ, but it’s worth a try.

→ Can I swap the glutinous rice flour out?

Stick with glutinous rice flour for that chewy bite. Regular rice or wheat flour won’t do. Tapioca starch could work but will change the texture a lot.

→ What’s a good dipping sauce option?

They’re tasty on their own, but you can dip them in honey, maple syrup, condensed milk, or even a light ginger syrup for extra flavor.
