Hey everyone, it’s Lin from Woks of Love! Whenever we have a heavy, rich meal like a hearty Corn and Pork Rib Soup or braised meats, I always like to serve a light, refreshing palate cleanser. Recently, a friend visited, and I whipped up this quick celery soup to pair with our fried rice noodles. After just one sip, she immediately asked for the recipe!
What makes this soup so amazing is that it is virtually zero-difficulty and uses no heavy seasonings—just a touch of salt. It relies entirely on the natural umami of the ingredients to create a beautiful, vibrant, and delicious bowl of comfort.
What Is Chinese Celery Soup (Qin Cai Geng)?
In Chinese cuisine, a “geng” (羹) refers to a soup that has been slightly thickened with a starch slurry, creating a smooth, velvety texture. This specific celery soup is designed to be highly visually appealing—with tiny, jewel-like dices of vibrant green celery, dark mushrooms, and delicate ribbons of egg white. It is incredibly soothing on the stomach and acts as the perfect counterbalance to greasy or spicy main courses.
If you enjoy this thick, silky texture, I highly recommend checking out my Seaweed Egg Drop Soup, which is another fantastic, quick homestyle recipe.

Ingredients
- Chinese Celery (Local Celery): 1.7 oz / 50 g (about 2 small stalks). Remove the leaves, but save 2 leaves for garnishing.
- Dried Shiitake Mushroom: 1 piece, soaked in warm water until soft.
- Zha Cai (Pickled Mustard Tuber): 0.35 oz / 10 g (about 1 slice).
- Ham Sausage: 0.5 oz / 15 g (about 1/4 of a standard small sausage).
- Water (for soup): 3 cups / 700 g.
- Salt: 1/2 tsp (or to taste). See my guide on choosing the right Salt.
- Egg White: 1/3 of an egg white.
- White Pepper (Optional): Just a pinch if you like a subtle kick. Read more about using White Pepper in Chinese cooking.
For the Starch Slurry:
- Cornstarch or Sweet Potato Starch: 1 tbsp / 15 g.
- Water: 2 tbsp / 30 g.
Equipment Needed
- A medium saucepan or wok.
- A wire whisk for creating fine egg ribbons.
- A sharp chef’s knife for precise mincing.
Prep & Mise en Place
Because the cooking process is so fast, having your ingredients prepped (mise en place) is essential.
- Soak the mushroom: Rehydrate the dried shiitake mushroom in warm water for about 20 minutes until fully softened.
- Fine mincing: Your knife skills will shine here. Mince the softened shiitake, Zha Cai, and ham sausage into very fine, uniform pieces (about 0.2 inch / 0.5 cm).
- Prep the slurry: In a small bowl, whisk together the 15g of starch and 30g of water until completely smooth.
- Separate the egg: Separate one egg, keeping only 1/3 of the egg white in a small bowl. Lightly beat it.
Cooking Process
Step 1: Blanch the Celery (1 Minute) Bring a small pot of water to a boil. Add a few drops of cooking oil and a pinch of salt. Drop in the celery stalks and blanch for exactly 60 seconds over medium-high heat.
“Blanching green vegetables in lightly salted water and immediately shocking them in cold water halts the enzyme actions that cause loss of flavor, color, and texture.”
Step 2: Ice Shock and Mince Remove the celery and immediately rinse it under cold running water (or submerge in an ice bath). Once cool, finely dice the celery stalks into 0.2 inch (0.5 cm) pieces. Finely chop the 2 reserved celery leaves.
Step 3: Build the Broth (1–2 Minutes) In a clean pot, bring the 3 cups (700 g) of water to a rolling boil. Add the minced shiitake mushrooms, Zha Cai, and ham. Let this boil for 1 minute to release their savory flavors into the water.
Step 4: Add Celery & Season Add the diced celery and 1/2 tsp of salt. Taste the broth here. Because the Zha Cai, ham, and mushrooms carry natural umami, you generally don’t need other seasonings, but you can adjust the salt to your preference.
Step 5: Thicken the Soup (1 Minute) Give your starch slurry a quick stir (the starch will have settled). Slowly pour the slurry into the gently simmering soup in batches, using a whisk to stir continuously until the soup turns slightly thick and glossy.
Step 6: Add the Egg White Ribbons (30 Seconds) While stirring the soup in a slow, circular motion, slowly drizzle in the 1/3 egg white. The movement will pull the egg white into beautiful, thin, silky ribbons.
Step 7: Garnish and Serve Turn off the heat. Stir in the minced celery leaves for a final pop of color. Serve immediately!
Why This Recipe Works
- Flavor Balance: The combination of Zha Cai (pickled mustard tuber), shiitake, and ham acts as a natural MSG substitute, providing deep savory notes without overpowering the light celery flavor.
- Texture Contrast: Shocking the celery keeps it incredibly crisp, contrasting beautifully with the velvety, thickened broth.
- Visual Appeal: Keeping the egg white quantity very small ensures the broth stays clear and doesn’t cloud the vibrant green of the celery.
Common Mistakes When Making Celery Soup
- Using the whole egg or too much egg white: If you use a whole egg or even a full egg white, the soup will become cloudy and yellow, hiding the beautiful green celery. Stick strictly to 1/3 of an egg white.
- Skipping the cold water shock: If you don’t rinse the blanched celery in cold water immediately, residual heat will overcook it. It will turn a dull olive-green and become mushy.
- Dumping the starch slurry all at once: This causes clumps. Always add it gradually while stirring constantly to ensure a smooth, restaurant-quality geng.
Frequently Asked Questions
Can I use regular Western celery? Yes, you can! However, Chinese celery (which has thinner, hollow stalks) is much more aromatic and delicate. If using Western celery, make sure to peel the tough outer strings before dicing.
Can I make this vegetarian/vegan? Absolutely. Simply omit the ham sausage. To replace the savory depth, you can add a few extra diced mushrooms or a tiny splash of Light Soy Sauce. (Omit the egg white for a vegan version).
Why do I need to add oil and salt when blanching? The oil coats the vegetable slightly, and the salt helps protect the chlorophyll molecules, keeping the celery a bright, appetizing green.
How to Serve
This soup is the ultimate supporting character for a larger meal. It pairs beautifully with savory, dough-based dishes like Pork and Vegetable Wontons or crispy Chinese Meat Pies. If you want to keep the entire meal light and vegetarian, serve it alongside some Homestyle Tofu and a crunchy Smashed Cucumber Salad.
Storage & Reheat
- Fridge: Store leftovers in an airtight container for up to 2 days.
- Freezer: Do not freeze this soup. The starch will break down and become watery upon thawing, and the crisp celery will turn to mush.
- Reheating: Reheat gently on the stovetop over medium-low heat. You may need to add a splash of water if the soup has thickened too much in the fridge.
Allergen Notice
- Gluten: Ham sausage and Zha Cai may contain traces of gluten or soy sauce.
- Soy: Zha Cai is often fermented with soy.
- Eggs: Contains egg white.

About the Author & Recipe Development
I’m Lin, and I grew up surrounded by the intense, bold flavors of Sichuan cooking. However, a chef knows that a well-rounded meal requires balance. I tested this recipe specifically to find the exact ratio of starch to water, ensuring the soup is silky but not gluey. I also experimented with the egg wash—using a full egg ruined the visual appeal, which is why I strongly advocate using only 1/3 of the egg white to achieve those perfect, delicate threads.
