Why I Fell for This Red Bean Sweet Potato Ball Soup (Even Though I’m Not a Dessert Person)
Let’s be real—I’ve never been the biggest dessert fan. Too sweet, too heavy, or just not worth the calories? Yeah, that’s usually me. But then I started scrolling through food blogs and TikTok, and every other post was someone making these colorful, squishy sweet potato or taro balls in a warm red bean soup. I couldn’t resist anymore! The way those balls looked so chewy and the red bean soup smelled so comforting… I had to try it.
Here’s the thing: everyone has their own twist. Some use glutinous rice flour, some use tapioca starch, and others mix tapioca with potato starch. I had no clue what the difference was, so I just grabbed the only starch I had at home—tapioca starch. Spoiler: it worked! The balls turned out perfectly QQ (that bouncy, chewy texture we all love) and soft. And since I don’t like super sweet stuff, I skipped sugar in the balls—they just tasted like the natural sweetness of sweet potato and purple sweet potato. If you have a sweet tooth, though, feel free to add a bit of sugar when making the dough!
What You’ll Need (No Fancy Ingredients, Promise)
Before we dive in, let’s gather the stuff. Most of these are pantry staples or easy to find at the grocery store:
- 300g orange sweet potato (the regular kind)
- 300g purple sweet potato
- 220g tapioca starch (100g for orange sweet potato, 80g for purple, 30g for dusting)
- 1 cup dried red beans (soaked overnight is best!)
- Rock sugar (adjust to your sweetness preference—remember, I used less!)
- Water (for boiling, steaming, and the soup)
Pro tip: Soak the red beans the night before. It cuts down the cooking time so much—trust me, I’ve forgotten before and it took forever.
Step-by-Step: Making the QQ Sweet Potato Balls & Red Bean Soup
Let’s break this into two parts: first the sweet potato balls, then the red bean soup. It’s easier than it looks, I swear!
Part 1: Making the Sweet Potato Balls (The QQ Star of the Show)
Step 1: Steam the Sweet Potatoes Until They’re Fork-Tender
Wash the orange and purple sweet potatoes, peel them, and cut into small chunks (smaller = faster steaming!). Pop them in a steamer basket and steam for 20 minutes. To check if they’re done, stick a fork in—if it goes in like butter, you’re good to go.
Step 2: Mash Them Until Silky Smooth (No Lumps Allowed!)
Put the steamed sweet potatoes into separate plastic bags (one for orange, one for purple—we don’t want purple staining the orange!). Grab a rolling pin (or a wine bottle, if that’s all you have) and mash them into a smooth paste. Make sure there are no big chunks—lumps will make the dough bumpy later.
Step 3: Mix in Tapioca Starch (This Is Where the QQ Magic Happens)
Transfer each mashed sweet potato into a big bowl. Add 100g of tapioca starch to the orange sweet potato, and 80g to the purple one. Stir gently at first—don’t worry if it looks crumbly at the start.
Step 4: Knead into a Dough (Patience Is Key Here)
Now, roll up your sleeves and knead the mixture into a dough. The goal is a dough that’s not sticky to the touch. If it’s too dry (like my orange sweet potato dough was!), add a tiny splash of water—just a teaspoon at a time. If it’s too sticky, add a little more tapioca starch. My purple sweet potato dough was perfect right away, but the orange one needed a splash of water. No biggie!
Step 5: Roll into Logs
Divide each dough into 3-4 small pieces. Take one piece and roll it into a thin log (about 1cm in diameter). The thinner the log, the smaller the balls—adjust based on how big you want them.
Step 6: Cut into Balls & Dust with Starch
Use a knife to cut the logs into 1cm pieces—these are your sweet potato balls! Toss them in the reserved 30g of tapioca starch to prevent sticking. If they look a little wonky, just roll them between your palms to make them round. Extra balls? Freeze them in a sealed bag—they’ll last for weeks!
Part 2: Making the Warm Red Bean Soup
Step 7: Cook the Red Beans Until Creamy
Take the soaked red beans (drain the water first!) and put them in a pot. Add enough water to cover the beans by 2 inches. Bring to a boil, then turn the heat down to low and simmer for 1-1.5 hours (or until the beans are soft and creamy). Add rock sugar 10 minutes before the end—taste as you go, since sweetness is personal!
Part 3: Putting It All Together (The Best Part!)
Step 8: Boil the Sweet Potato Balls
Fill a pot with water and bring to a rolling boil. Add the orange sweet potato balls first (they cook faster) and boil for 2 minutes. When they float to the top, they’re done!
Step 9: Ice Them for Extra QQ Texture
Use a slotted spoon to transfer the cooked balls to a bowl of ice water. Let them sit for 1 minute—this is the secret to making them super chewy! Trust me, don’t skip this step.
Step 10: Boil the Purple Sweet Potato Balls
Repeat Step 8 with the purple sweet potato balls—boil for 2 minutes until they float.
Step 11: Ice the Purple Balls Too
Transfer the purple balls to the ice water, then drain both colors well.
Step 12: Assemble & Enjoy!
Ladle the warm red bean soup into a bowl. Add a handful of orange and purple sweet potato balls. Take a bite—warm, creamy soup with bouncy, naturally sweet balls. It’s so cozy, especially on a cold day!
My Top Tips for Success (From Someone Who Made Mistakes)
- Don’t overmix the dough! Too much kneading can make the balls tough.
- Steam the sweet potatoes separately if your steamer is small (like mine!). Purple sweet potato will stain orange if they touch.
- Adjust sugar to your taste! I used less rock sugar because I like the natural sweetness of the sweet potatoes, but add more if you want it sweeter.
Final thought: This recipe is so forgiving. Even if your balls aren’t perfectly round or your dough is a little sticky, it’ll still taste amazing. Give it a try—you might just become a dessert person after all!
