What Are Sweet Potato Balls? A Guide to Singapore's Beloved Dessert

The question that started our business, basically. My mother-in-law used to make sweet potato balls every time the family gathered — Christmas, Chinese New Year, random Sundays when she felt like it. The kids loved them, the adults loved them, and nobody could ever explain to friends what they were. "It's like... mochi? But not? Made from sweet potato? It's chewy? Just try one."

Eventually we decided to stop trying to explain and start selling them. But we still get the question all the time: what exactly are sweet potato balls?

TL;DR: Sweet potato balls (fan shu yuan) are a traditional dessert made with real taro and sweet potato, served in comforting green bean soup. They are boiled, not fried, and have a soft, chewy QQ texture.

The Basics

Sweet potato balls — known in Hokkien as fan shu yuan or oo ni yuan (for taro) — are small, round balls made from mashed sweet potato or taro mixed with tapioca flour. The tapioca flour gives them their signature QQ texture: soft, bouncy, slightly chewy. The kind of bite that makes you understand why Singaporeans have a whole vocabulary for describing mouthfeel.

They are served in warm dessert soup. The most common pairing in Singapore is green bean soup (luk tau tng) — slow-cooked mung beans and rock sugar. Other pairings: ginger syrup, peanut soup, coconut milk.

What They Are Like

• Texture: Soft and chewy (QQ) — bouncy without being rubbery
• Flavour: Subtly sweet, natural taste of sweet potato or taro
• Colour: Natural — orange-yellow from sweet potato, purple-grey from taro
• Size: Bite-sized, about 2-3 cm across
• Serving: Warm, in dessert soup

How They Are Made

The method is simple in concept but takes practice to get right.

Ingredients

At its core: sweet potato or taro, tapioca flour, and a pinch of sugar. That is it. No eggs, no dairy, no wheat flour. Naturally gluten-free and suitable for most common food allergies.

The Process

1. Steam the sweet potato or taro until completely soft
2. Mash while warm — smooth consistency matters
3. Mix in tapioca flour gradually — the ratio is everything. Too much flour makes them hard. Too little and they fall apart in the soup
4. Knead the dough until smooth and pliable
5. Roll into small balls by hand — each one about the size of a large marble
6. Cook by dropping into boiling water or directly into the soup

The hand-rolling is where experience really matters. Each ball needs to be uniform so they cook evenly. At Ah Ma QQ Bowl, every single ball is hand-rolled — we do not use machines or moulds. It is slower, but you can feel the difference when you eat them.

Why Green Bean Soup?

Green bean soup is the classic partner. Made from mung beans slow-cooked with rock sugar and sometimes pandan leaves, it has a gentle sweetness and comforting warmth that complements the chewy balls perfectly.

The combination works because of contrast: smooth, liquid soup against bouncy, textured balls. Mung beans add subtle earthiness. Rock sugar provides clean sweetness that does not overpower the natural flavour.

Rock Sugar vs White Sugar

Traditional recipes insist on rock sugar. It dissolves more slowly, produces cleaner sweetness, and gives the soup a slightly glossy appearance. We use rock sugar exclusively. The difference is noticeable — white sugar makes the soup cloying, rock sugar keeps it light.

Why They Matter

Sweet potato balls are more than dessert in Singapore. They carry cultural weight, especially among older Hokkien and Teochew communities.

A Symbol of Home

For many Singaporeans, sweet potato balls mean grandmothers in the kitchen. The dessert is strongly associated with home cooking, family gatherings, and the kind of food that never needed a recipe written down because everyone in the family just knew how to make it. That is literally how our business got its name.

Festive Connections

They appear during Chinese New Year, Lantern Festival, and Winter Solstice (Dong Zhi). The round shape symbolises reunion and completeness. During Dong Zhi, eating round dessert balls represents growing one year older and wiser.

Comfort Food

Like all great comfort food, sweet potato balls are warm, simple, and deeply satisfying. The kind of thing people turn to when they want something familiar and nourishing.

Sweet Potato vs Taro: What Is the Difference?

We make both, and people often ask how they compare:

Sweet Potato Balls

• Colour: Orange to golden yellow
• Flavour: Naturally sweeter, mild caramel-like taste
• Texture: Slightly softer and more delicate

Taro Balls

• Colour: Light purple to grey
• Flavour: More earthy and nutty, less sweet
• Texture: Slightly denser and more substantial

Our signature product combines both — taro and sweet potato balls together in green bean soup. Best of both varieties in every packet.

Where to Find Them in Singapore

• Hawker centres — Some traditional dessert stalls serve them, though they are becoming rarer as older hawkers retire
• Home kitchens — Many families still make them from scratch during festivals
• Online delivery — Frozen options like ours make it easy to enjoy at home anytime

The hawker scene for traditional handmade desserts has been declining. Fewer operators specialise in these labour-intensive items. That is one of the reasons we started — to keep the recipe alive and accessible.

Why Frozen Works

You might wonder if frozen can really compare to fresh. It can — when done right.

The key is flash-freezing shortly after preparation, which locks in texture and flavour. When you reheat, the tapioca flour rehydrates naturally and you get the same QQ texture as freshly made.

Advantages:

• Ready in minutes
• Consistent quality every time
• No preservatives needed — freezing is natural preservation
• Keeps for 3 months

We prepare fresh, flash-freeze immediately, and deliver frozen. The result tastes like home kitchen food — because it is.
