Frequently Asked Questions

Q

How much shrimp do I need for har gow?

Each har gow uses about 10.5g of peeled shrimp (70% of the 15g filling). For 24 dumplings, that is 252g peeled shrimp. Since shelling removes 30–40% of weight (depending on size), buy 350–380g of shell-on shrimp. Large (21–30 count) shrimp work best for the right texture.

  • Per dumpling: 10.5g peeled, deveined shrimp (70% of filling)
  • Batch of 24: 252g peeled = ~353g shell-on (large shrimp)
  • Medium (31-40 count): 50% waste from shell/head
  • Large (21-30 count): 40% waste from shell/head
  • Jumbo (16-20 count): 35% waste from shell/head

Q

What is har gow wrapper dough made of?

Har gow wrappers use wheat starch (not flour) and tapioca starch mixed with boiling water and a little oil. The ratio per dumpling is 5.5g wheat starch, 2g tapioca starch, 2.2ml boiling water, and a drop of oil. Boiling water is essential—it gelatinizes the starch to create the translucent, stretchy skin.

  • Per wrapper: 5.5g wheat starch + 2g tapioca starch
  • Boiling water: 2.2ml per wrapper — must be boiling, not warm
  • Oil: 0.3ml per wrapper (vegetable or sesame)
  • The dough must be worked while hot — it hardens when cool
  • Roll wrappers thin (2mm) for the signature translucent appearance
Q

What is in har gow filling besides shrimp?

Authentic har gow filling is 70% shrimp, 15% bamboo shoots, 10% pork back fat, and 5% seasonings. The bamboo shoots add crunch, pork fat adds juiciness, and seasonings include sesame oil, white pepper, sugar, and cornstarch. The shrimp should be a mix of diced and whole for texture contrast.

  • Shrimp: 70% of filling — mix of coarsely chopped and whole pieces
  • Bamboo shoots: 15% — finely diced for subtle crunch
  • Pork back fat: 10% — minced, adds juiciness (omit for lighter version)
  • Seasonings: 5% — sesame oil, white pepper, sugar, cornstarch
  • Add cornstarch to filling to bind and retain juices during steaming
Q

How long do I steam har gow?

Steam har gow for exactly 8 minutes over high heat. The wrappers should turn from white to translucent, with the pink shrimp visible inside. Over-steaming makes wrappers gummy, and under-steaming leaves them opaque and raw-tasting. Place on parchment to prevent sticking.

  • Steam time: 8 minutes over high heat, lid tightly closed
  • Done when: wrappers turn from opaque white to translucent
  • Pink shrimp should be clearly visible through the wrapper
  • Line steamer with parchment circles or oiled cabbage leaves
  • Serve immediately — har gow wrappers harden as they cool
