Cantonese Clear Broth (Pork Bone to Water)

300g per 500g total

Pork neck bones or spine (龍骨) — Primary bones; medium gelatin, clean sweet pork flavour without excessive fat

100g per 500g total

Pork knuckle or trotter (豬手) — Adds body and gelatin; use sparingly to avoid muddying the flavour

100g per 500g total

Pork fillet or lean offcuts — Optional; some Cantonese cooks add a piece of lean meat for sweetness and protein clarity

1 litre per 500g bones

Cold water — Start cold; the gradual temperature rise draws impurities to the surface

3–4 slices (about 15g) per litre

Ginger slices — Essential for deodorising; added before the first blanch and again during the main simmer

2–3 pieces per litre

Dried dates or dried longan (optional) — Cantonese tonic additions for sweetness and a subtle herbal note

Place bones in a large pot, cover with cold water, bring to a rolling boil and blanch for 5–8 minutes until grey scum rises freely. Drain completely, rinse each bone under cold running water, and scrub away any remaining blood or marrow residue. Return cleaned bones to the pot with fresh cold water at the 500g:1L ratio. Add ginger. Bring very slowly — over 20–30 minutes — to the gentlest possible simmer (approximately 85 °C). Skim constantly for the first 15 minutes. Maintain at a bare tremble, never a boil, for 2–3 hours. Strain through a fine-mesh sieve lined with cheesecloth. The finished broth should be clear gold; if cloudy, bring to a bare simmer and skim once more, or clarify with a clearmeat.

• The blanching rinse is non-negotiable in Cantonese cooking — every bone must be rinsed individually to remove blood trapped in marrow cavities, or the finished broth will carry a grey colour and metallic undertone.
• Temperature discipline is the single biggest clarity variable: a vigorous boil for even five minutes will permanently cloud a Cantonese broth by emulsifying fat droplets into the liquid.
• Do not stir the pot during simmering; disturbing the sediment layer that collects on the bottom will cloud the broth.
• A small piece of Jinhua ham (金華火腿) or Chinese cured pork dramatically deepens flavour without adding colour — a trick used in Cantonese restaurants for 'white stock' that tastes unusually complex.
• Cool the finished broth rapidly in an ice bath, then refrigerate. Remove the solidified fat cap before reheating, which yields a leaner, cleaner-tasting broth.

• Double-blanch method

  Blanch twice — once briefly to remove blood, a second time for 20 minutes to set the proteins — for an exceptionally clean, colourless stock used in restaurant wonton soups

• Corn and pork bone soup (粟米豬骨湯)

  Add 2 ears of corn per litre during the final hour; sweetness balances the savouriness, a classic Cantonese home-style soup served as a course not a stock base

• Watercress and pork bone soup (西洋菜豬骨湯)

  A full bunch of watercress added in the last 30 minutes; prized as a lung-tonic tāng in Cantonese health cuisine

• Superior stock (上湯)

  Combines pork bones, whole chicken, Jinhua ham, and dried scallops at a 2:1:0.3:0.1 ratio; intensely flavoured restaurant-grade stock used in superior soups and high-end braises

• Congee base

  Reduce the standard broth by one-third and use in place of water for jook; produces a richer, more savoury congee

• Consommé clarification ratio

  Cantonese superior stock is sometimes clarified via clearmeat for formal banquet soups, using the same lean-meat raft principle as French consommé

• Congee (jook) liquid ratio

  1 part rice to 10–12 parts Cantonese pork broth is the standard jook ratio, where the broth quality is decisive
