Chinese Watercress Soup
Growing up, this comforting Chinese watercress soup was a staple on our family dinner table. Known traditionally in Cantonese as Sai Yeung Choy Tong (西洋菜汤), my mom made it for us whenever we needed a light, refreshing meal, and now I cook it the exact same way in my own home. Many traditional recipes call for boiling the greens with pork bones for hours until the leaves turn dark brown, but my mom’s version proves you do not need heavy bone broth to make a deeply delicious soup. This quick method takes just 25 minutes, using the natural sweetness of jujubes and goji berries to balance the fresh, peppery bite of the vegetables perfectly.
I know some people think a quick boil makes the liquid taste thin, but skipping the long simmer actually keeps the flavors clean and prevents the watercress from turning unpleasantly bitter. If you follow my foolproof steps, the water extracts the clean essences of the greens and dried fruits instantly, giving you a beautiful, clear broth that feels incredibly light and nourishing. It is a simple weeknight side dish that pairs beautifully with Steamed Fish, classic stir-fries like my Kung Pao Chicken or Sesame Oil Chicken, and a hot bowl of jasmine rice.
Shopping Guide: Choosing Your Ingredients
Getting a clear, sweet broth depends entirely on what you put in the pot. Here is what you need to look for when you buy your ingredients.
How To Choose Fresh Watercress
- Look for bright green leaves and thin, crisp stems.
- Skip bundles with yellow spots or slimy leaves. That means they are already turning bad.
- Go for young watercress instead of mature ones. You can easily tell them apart by the stems. Young watercress has thin, solid, flexible stalks and small, delicate leaves that cook through quickly.
- Avoid the mature bunches that have thick, wide stems that are completely hollow inside. Also pass on any that have tiny white flowers blooming at the tips. Those are way too woody, stringy, and bitter for a quick boil.
- Wash them thoroughly in a big bowl of cold water to get rid of any hidden dirt or grit before you chop them into two-inch pieces.
Sidenote: In Chinese tradition, watercress is excellent for clearing internal heat and soothing the lungs. It is also packed with vitamins C and K to keep your immune system strong.
Buying The Best Red Dates
- Get the pitless red dates because they save you a ton of prep time and make the soup much easier to eat.
- Give them a quick twist and tear them open slightly with your fingers right before you drop them into the boiling water.
- Breaking the skin opens up the fruit, letting all that deep, natural caramel sweetness flood into your broth immediately without needing hours of boiling time.
Sidenote: Chinese red dates are highly valued for nourishing the blood, boosting your daily energy levels, and improving overall circulation.
Spotting High Quality Goji Berries
- Check the label for Ningxia, China. This specific region produces the absolute highest quality goji berries you can buy.
- Give the package a sniff. Good goji berries should smell naturally sweet and fruity. If you catch a sharp, sour, or chemical odor, put them right back.
- Spend a little extra cash for the premium brands. Cheap, low-quality options are usually treated with sulfur dioxide to make them last longer.
- Look closely at the seeds. You can easily spot sulfur-treated berries because their tiny inner seeds turn a dark black color.
- Stick to a natural orange-red color. High-quality berries look a bit matte and dark. Be careful if they look suspiciously bright neon red and perfect, as those are usually treated with artificial dyes.
Sidenote: Clean goji berries are loaded with vision-supporting antioxidants, help lower inflammation, and naturally strengthen your body.
Storage Tip: Once opened, always keep your red dates and goji berries in a sealed container inside the fridge. If you leave them out, they will oxidize quickly, turn dark brown, and lose their natural sweetness.
Ingredients You’ll Need
- Watercress
- Dried red dates
- Dried goji berries
See the recipe card below for all the ingredient details and exact measurements.
Pro Tip #1: Wash The Dried Fruits First
Do not skip rinsing the red dates and goji berries under cold water. They pick up a lot of dust during the sun-drying and packaging process, and a quick wash keeps that grit out of your clean broth.
Pro Tip #2: Go for Fresh Fish Balls
If you want to add fish balls, buy the fresh, vacuum-sealed packs in the fridge section instead of the frozen ones. Give the bag a light squeeze. You want them to feel firm and springy so they keep that nice, snappy bite when they heat through. If you can only find frozen ones, just thaw them completely before throwing them into the pot so they cook evenly without getting mushy.
Pro Tip #3: Make It Plant-Based
You can easily leave the fish balls out to make this dish completely vegetarian and vegan. The broth gets plenty of great flavor just from the greens and dried fruits alone.
How To Make Watercress Soup
Bring a large pot of water to a rolling boil over high heat.
Drop in your watercress, using a ladle or tongs to press the greens down until they are fully underwater. Toss in your red dates and goji berries right after.
Pro Tip: Do not cover the pot. Leaving the lid off lets the harsh bitterness cook off into the air, keeping your broth perfectly sweet and clean.
Let the water come back to a boil until the watercress wilts down. Turn the heat down to a gentle simmer and skim off any foam that floats to the top. Keep simmering, skimming once in a while, until the greens reach the texture you like. Give it about 10 minutes if you want a bit of a crunch, or 15 minutes if you prefer them soft.
Pro Tip: If you want that softer texture, keep an eye on your water level as it bubbles away. You want to make sure the greens stay completely covered so they cook evenly.
Drop in your fish balls, if using, and let them cook for about 3 minutes until they heat through. Season the broth with salt to taste and serve it up hot.
Frequently Asked Questions
Yes, the whole vegetable is edible. Slicing the stems into shorter, two-inch pieces makes them much easier to chew once they soften up in the broth.
You do not have to, but de-seeded dates make the soup much easier to eat. If your dates still have pits, just slice them down the middle to pop the seeds out before cooking.
Yes. Sliced pork loin, chicken, or ribs are classic additions. If you use raw meat, boil it first and skim off the scum before adding your watercress and dried fruits.
Yes. Put the water, red dates, and goji berries in first on high for two hours. Toss the watercress in during the last 30 minutes, and add the fish balls in the final 5 minutes.
Store the soup in an airtight container in the fridge for up to two days. Reheat it on the stove over medium heat until hot. Try not to overcook it, or the watercress will turn completely mushy.
