Direct answer: Cantonese winter melon soup stays clear and delicate when the broth is kept at a gentle simmer, the meatballs are cooked before the melon, and winter melon is added only for the final 10 to 15 minutes. Cut equal pieces and stop when they turn translucent but still hold their shape. Ground-pork meatballs must reach 160°F/71°C.
Key takeaways
- Peel away winter melon's hard green skin and seed cavity.
- Keep the broth below a hard boil for a clear finish.
- Mix meatballs until tacky but do not compact them.
- Add melon late because it softens quickly.
- Check ground pork with a thermometer, not color alone.
What is Cantonese winter melon soup?
Winter melon, or dong gua, is a large pale-fleshed gourd with a mild flavor. In Cantonese soup it absorbs the broth and becomes translucent. This everyday version combines a clean ginger broth, tender pork meatballs and a small amount of dried shrimp for savoriness.
The name refers to the mature melon keeping well into winter, not to a cold soup. It is served hot and should taste light rather than heavily seasoned.
Ingredients for 4 servings
Meatballs
- 8 ounces/225 g ground pork, about 80% lean
- 1 teaspoon light soy sauce
- 1 teaspoon Shaoxing wine
- 1 teaspoon cornstarch
- 1/2 teaspoon sesame oil
- 1/4 teaspoon salt
- 2 tablespoons cold water
- 1 teaspoon grated ginger
Soup
- 1 1/2 pounds/680 g winter melon before trimming
- 6 cups/1.4 L unsalted chicken stock or water
- 1/4 cup/20 g dried shrimp, rinsed and soaked 15 minutes
- 5 ginger slices
- 2 scallions, sliced
- 1/2 teaspoon white pepper
- Salt to taste
Allow 20 minutes preparation and about 25 minutes cooking.
How to choose and cut winter melon
Choose a cut section with firm white flesh, no sour smell and no wet, collapsing patches. Whole mature melons have a waxy dark-green rind. Refrigerate cut melon and use it promptly.
Remove the hard skin with a sturdy knife, then scrape out seeds and spongy center. Cut the firm flesh into 1-inch/2.5-cm cubes. Equal pieces finish together.
Step 1: mix tender meatballs
Combine pork, soy sauce, wine, cornstarch, sesame oil, salt and ginger. Stir in one direction for 45 seconds. Add cold water one tablespoon at a time and continue until the mixture looks tacky.
Chill for 15 minutes. The mixture should hold a rounded teaspoon without flowing. Do not add breadcrumbs; they cloud the broth and change the texture.
Step 2: build a clean broth
Bring stock, ginger and drained dried shrimp to a boil in a 3-quart pot. Immediately reduce to a gentle simmer and cook uncovered for 8 minutes. Skim foam if it appears.
Do not use the shrimp soaking water unless it has been filtered and tastes clean; grit can settle at the bottom. Unsalted stock allows better control because dried shrimp contributes salt.
Step 3: poach the meatballs
Wet two teaspoons and form 12 small meatballs, about 2 teaspoons each. Lower them into barely bubbling broth. Simmer for 6 to 8 minutes, turning once, until they float and reach 160°F/71°C in the center.
Floating is not a complete safety test. Check the largest meatball with an instant-read thermometer. Remove surface foam for a clearer soup.
Step 4: add winter melon at the right time
Add winter melon and return the soup to a gentle simmer. Cook 10 to 15 minutes. It is ready when the edges look translucent and a fork enters with light resistance.
Do not cook until the cubes disintegrate. Carryover heat continues softening them after the burner is switched off.
Step 5: season last
Add white pepper and taste the broth before adding salt. Finish with scallions and rest 2 minutes. Remove ginger slices if desired, then divide melon, meatballs and broth evenly among bowls.
How to keep the broth clear
Use a gentle simmer, skim foam, and avoid stirring repeatedly. A rolling boil emulsifies pork fat and particles into the liquid. Cloudiness is not unsafe, but it changes the intended delicate presentation.
Clear stock also matters. If homemade stock contains sediment, strain it through a fine sieve before cooking.
Substitutions
Without dried shrimp
Omit it and add two soaked dried shiitakes, thinly sliced. The soup will be earthier but remains savory.
Chicken meatballs
Use ground chicken with some thigh meat and cook to 165°F/74°C. Very lean breast meat can become firm.
Vegetarian soup
Use vegetable stock, shiitakes and firm tofu cubes. Add tofu with the winter melon and simmer gently.
No Shaoxing wine
Replace it with cold water. Do not use equal rice vinegar, which is much more acidic.
Common mistakes
The winter melon falls apart
Pieces were too small or cooked too long. Use 1-inch cubes and begin checking at 10 minutes.
The meatballs are tough
The pork was too lean, compacted firmly or boiled aggressively. Use moderate fat and a gentle simmer.
The soup tastes fishy
Dried shrimp may be old or used in excess. Rinse, soak and use only 1/4 cup.
The broth is bland
Salt may be low, but add it only after the shrimp and meatballs cook. White pepper and scallions should support, not dominate, the melon.
Food safety and storage
Keep raw ground pork at 40°F/4°C or below and prevent contact with ready-to-eat foods. USDA guidance specifies 160°F/71°C for ground pork. Wash tools and hands after handling it.
Refrigerate soup within 2 hours in shallow containers and use within 3 to 4 days. Reheat to 165°F/74°C. Winter melon softens after repeated heating, so warm only the portion needed.

FAQ
Is winter melon sweet?
No. Its flavor is mild and vegetal, and it absorbs savory broth.
Can I eat the skin?
Mature winter melon skin is hard and is normally removed for this soup.
Can I make the soup ahead?
Yes, but slightly undercook the melon and reheat only once for the best shape.
Why are my meatballs breaking?
The pork was not mixed until tacky or the broth boiled too hard. Chill the mixture and poach gently.
Can I freeze it?
The soup is safe to freeze, but thawed winter melon becomes softer. Freeze the broth and meatballs separately when texture matters.
Conclusion
Clear winter melon soup depends on gentle heat and ingredient timing. Cook small meatballs safely, add equal melon cubes late and season only after dried shrimp has flavored the broth. Our homemade Chinese cooking courses demonstrate soup clarity, meatball texture and doneness checks visually.
