Har Gow

Har gow is the crown jewel of Cantonese dim sum, the dish by which dumpling masters have always been judged. The hallmark is a translucent, slightly chewy wheat-starch wrapper — pleated into at least seven precise folds — encasing a plump, springy whole-shrimp filling. Eaten fresh from bamboo steamers at weekend yum cha, it remains one of the purest pleasures of Cantonese cuisine.

Serves: 4 (makes about 24 dumplings)

Ingredients

Dough

• 200g (1⅓ cups) wheat starch (tang mian fen / 澄粉)
• 40g (¼ cup) tapioca starch
• ½ tsp fine salt
• 220ml (¾ cup + 1 tbsp) boiling water
• 1 tsp (5ml) neutral oil

Filling

• 300g (10 oz) raw tiger prawns, peeled and deveined, cut into chunks
• 100g (3.5 oz) raw prawns, roughly chopped (for binding)
• 1 tbsp (15ml) oyster sauce
• 1 tsp (5ml) sesame oil
• 1 tsp cornstarch
• ½ tsp fine sugar
• ¼ tsp white pepper
• 50g (1.8 oz) bamboo shoots, finely diced

Instructions

1. Combine wheat starch, tapioca starch, and salt. Pour boiling water over all at once, stirring rapidly with a fork. Cover and rest 2 minutes, then knead in the oil until smooth, about 3 minutes. Keep covered with a damp cloth at all times.
2. Mix both portions of prawns with oyster sauce, sesame oil, cornstarch, sugar, white pepper, and bamboo shoots. Stir briskly in one direction for 1 minute to develop a springy texture. Refrigerate 20 minutes.
3. Divide dough into 24 pieces (about 11g each). Using a lightly oiled cleaver or flat of a knife, press each piece into a thin round about 9cm (3.5 inches) across.
4. Place a heaped teaspoon of filling in the center of each round. Fold wrapper in half and make 7–10 pleats along the front edge, pressing to seal. The finished dumpling should be a curved crescent.
5. Line bamboo steamers with parchment. Arrange dumplings without touching. Steam over vigorously boiling water for 7–8 minutes until wrappers turn translucent and filling is cooked through.
6. Serve immediately with light soy sauce and chili oil.

Cook's Notes: Wheat starch (澄粉) is non-negotiable — it is the gluten-free starch component of wheat and creates the translucent wrapper. The dough must stay warm and covered; it dries and cracks within minutes. Work quickly.
