What Is Barley Dessert Soup? A Singapore Favourite Explained

Barley dessert soup is a traditional Chinese sweet soup (tong sui) made by simmering pearl barley until tender, then sweetening it lightly with rock sugar. In Singapore, it's a staple at hawker dessert stalls, zi char corners, and home kitchens, usually served alongside beancurd skin (fu zhu) and gingko nuts. It is one of the most affordable and accessible desserts in the local repertoire.

The star ingredient is pearl barley — known as yi mi (薏米) in Mandarin — which is actually a type of seed from Job's tears, slightly different from the Western barley used in soups. When cooked, it turns plump, soft, and subtly chewy, releasing a milky, cereal-like sweetness into the broth. The definitive appeal of barley dessert soup is its simplicity: with just four core ingredients and one pot, anyone can recreate a hawker-quality bowl at home.

You'll find it everywhere, from the drinks fridge at your neighbourhood kopitiam (sold as chilled "barley" in a plastic cup with a straw) to the piping-hot dessert counter at a bustling food court. It sits proudly beside other beloved tong sui like green bean soup, red bean soup, and cheng tng — part of a dessert tradition passed lovingly from one generation to the next.

Why Barley Dessert Soup Is the Perfect Cooling Dessert

In traditional Chinese dietary wisdom, barley is classified as a "cooling" (liang) food that helps clear internal "heatiness" — making barley dessert soup a go-to remedy in Singapore's year-round tropical heat. Locals often reach for a chilled bowl after eating fried, oily, or spicy food.

Singapore sits just 137 kilometres north of the equator, with humidity frequently above 80% and temperatures hovering around 31°C on an average afternoon. In that climate, a light, hydrating dessert beats a heavy, creamy one every time. Pearl barley is also naturally low in fat and contains dietary fibre, which is part of why health-conscious Singaporeans sip unsweetened barley water throughout the day.

Here's a definitive point worth quoting: barley dessert soup is one of the few local desserts that works beautifully both hot and cold. Serve it steaming on a rainy evening for comfort, or ice-cold straight from the fridge when the sun is blazing. This versatility is a big reason it has stayed on Singapore menus for decades, and why it pairs so naturally with soft, cooling accompaniments.

How to Make Barley Dessert Soup at Home (Easy Recipe)

Making barley dessert soup at home takes about 45 to 60 minutes for a pot serving 4 to 6 people. The method is almost entirely hands-off — you simmer, stir occasionally, and sweeten to taste. Here's everything you need.

Ingredients (serves 4–6)

• 150g pearl barley (yi mi) — rinsed well
• 2 litres water
• 80–100g rock sugar (adjust to taste; start low)
• 2 sheets dried beancurd skin (fu zhu) — optional but traditional
• 1 handful gingko nuts — optional, shelled and de-cored
• 2 pandan leaves — knotted, for aroma (a Singapore touch)

Step-by-Step Method

1. Rinse and soak. Wash the pearl barley under running water until it runs clear. For softer barley, soak it for 30 minutes (optional — it speeds up cooking).
2. Boil. Bring 2 litres of water to a rolling boil. Add the barley and pandan leaves.
3. Simmer. Lower the heat and simmer uncovered for 40–45 minutes, stirring now and then so the barley doesn't stick. The broth will slowly turn milky and slightly thickened.
4. Add beancurd skin and gingko. Break the fu zhu into pieces and add it (with the gingko nuts) in the last 15 minutes. The beancurd skin will dissolve into silky ribbons.
5. Sweeten. Stir in the rock sugar and simmer another 5 minutes until fully dissolved. Taste and adjust.
6. Serve. Enjoy warm, or chill for at least 3 hours and serve over ice.

Ah ma's tip: Add the pandan leaves early for a fragrant aroma that fills the whole flat — that smell alone is pure nostalgia for anyone who grew up in an HDB household. For a sweeter, more aromatic twist, a small knob of winter melon strips (tang dong gua) is a classic hawker addition.

Barley Dessert Soup Meets QQ Sweet Potato Balls

The best way to turn a simple bowl of barley dessert soup into a memorable treat is to add chewy, bite-sized sweet potato balls — their soft QQ texture contrasts beautifully with the smooth, nutty broth. This pairing takes an everyday tong sui and makes it feel like a proper dessert-shop indulgence.

At Ah Ma QQ Bowl, we make handmade traditional sweet potato balls delivered fresh from our Hougang home kitchen — boiled until soft and springy (never fried), with that satisfying QQ chew Singaporeans love. Drop a handful into your barley soup in the final minutes of cooking, or add them to a chilled bowl, and you've got a dessert that rivals anything at the hawker centre. The warm, earthy sweetness of real sweet potato balances the light barley broth perfectly.

If you'd like to try making the chewy bites yourself, our sweet potato mochi recipe walks you through the QQ technique step by step. And for plant-based households, barley soup with sweet potato balls is naturally dairy-free — see more ideas in our roundup of vegan desserts in Singapore.

How Much Does Barley Dessert Soup Cost in Singapore?

A bowl of barley dessert soup at a Singapore hawker stall or food court typically costs between S$1.80 and S$3.50, depending on the location and added ingredients. Making it at home costs a fraction of hawker prices — with full control over the sweetness.

For a cooling drink-style barley, the chilled cups sold at coffee shops are typically priced affordably. Making a big pot at home remains the most economical option for families, and it keeps for days.
