What is Tangzhong?

Tangzhong (湯種) is an Asian bread-making technique — sometimes called a water roux — in which a small portion of a recipe's flour and liquid are cooked into a thick paste before being added to the final dough. The technique was popularized in the 1990s by Chinese writer Yvonne Chen in her book The 65° Bread Doctor, named after the critical starch gelatinization temperature of 65°C / 149°F.

When flour and water are heated past 65°C, the starch granules absorb and lock in water, swelling into a smooth, glossy paste. This trapped moisture stays bound within the dough even during baking — creating what bakers call stealth hydration: a dough that is technically wetter but still easy and comfortable to handle.

✦ What it does to your bread
  • Softer, more tender crumb — the additional bound moisture tenderizes the gluten network
  • Extended shelf life — bread stays soft and moist for several days longer than an equivalent loaf without it
  • Better oven spring — higher hydration produces more steam during baking, lifting the loaf
  • Easier handling — despite being higher hydration overall, the dough feels less sticky and more workable
⚠ When not to use it

Tangzhong suits enriched, soft breads: sandwich loaves, dinner rolls, brioche, pain de mie, cinnamon rolls, milk bread, and hamburger buns. It is not recommended for lean artisan breads like baguettes or open-crumb sourdoughs — the tenderizing effect works against the chewy crumb and crisp crust you want.

Incorporating Tangzhong Into an Existing Recipe

The tangzhong uses flour and liquid already in your recipe — you are not adding extra. Both the flour and the liquid for the tangzhong must be subtracted from your original recipe amounts before mixing the final dough.

Use 5–10% of the total recipe flour weight for the tangzhong, combined with 5× that flour weight in liquid. Starting at 7% is a reliable middle ground. Going above 10% can cause the crumb to become dense and tight.

Cooking Instructions

  1. 1
    Weigh out the tangzhong flour and liquid into a small saucepan. Whisk together until smooth and lump-free — do this before applying any heat.
  2. 2
    Place over medium-low heat. Whisk constantly as the mixture warms — do not walk away.
  3. 3
    Cook until the mixture reaches 65°C / 149°F. Visual cue: the paste thickens noticeably and a spatula leaves clean lines that hold. Typically 2–4 minutes.
  4. 4
    Remove from heat immediately. Do not cook past 149°F — overheating dries out the paste.
  5. 5
    Press plastic wrap directly onto the surface. Cool completely to room temperature before adding to dough. May be refrigerated, covered, for up to 2–3 days.
  6. 6
    When mixing the final dough, use the adjusted flour and liquid amounts from the calculator below. Add the cooled tangzhong paste along with the remaining ingredients.

Use this when your recipe lists a total finished tangzhong amount rather than the individual flour and liquid components. Enter the total and this will break it back down for you.


Breakdown

Based on the standard 1:5 flour-to-liquid ratio (1 part flour + 5 parts liquid = 6 parts total tangzhong).

Tangzhong Flour Component
35.0 g
Tangzhong Liquid Component
175.0 g

These are the raw ingredient weights to combine before cooking. Cook to 65°C / 149°F until thickened. The finished paste will weigh slightly less than the total due to evaporation.

Standard Loaf Pans

Open-top pans where dough crowns above the rim.

PanDimensionsWhite / SourdoughWhole Wheat
Mini Loaf5.75" × 3" × 2"200–250 g250–300 g
Small Loaf8.5" × 4.5" × 2.75"450–550 g550–650 g
Standard Loaf9.25" × 5.25" × 2.75"680–800 g800–950 g
Large Loaf10" × 5" × 3"900–1,000 g1,000–1,150 g
Extra Large Loaf12" × 5" × 3"1,100–1,200 g1,200–1,400 g
✦ What drives the range
  • Flour type — Whole wheat rises less; needs 15–25% more dough for the same pan
  • Hydration — Higher hydration means more oven spring; less dough can produce the same finished height
  • Crown preference — More dough yields a higher dome; less gives a flatter, sandwich-friendly top
  • Enrichment — Butter, milk, and eggs often improve rise and allow slightly less dough
  • Baking loss — Most breads lose ~10–12% of pre-bake weight to evaporation during baking

Pullman / Pain de Mie Pans

Closed-lid pans requiring more precise dough weight to achieve a square, even loaf profile.

PanDimensionsWhite BreadWhole WheatHigh Rye
Small Pullman9" × 4" × 4"720–870 g900–1,100 g1,050–1,250 g
Large Pullman13" × 4" × 4"1,040–1,250 g1,200–1,400 g1,400–1,650 g
✦ What drives the range
  • Flour type — The biggest factor. Whole wheat needs 15–30% more dough; high-rye doughs need the most
  • Hydration — Higher hydration produces more oven spring, so slightly less dough fills the same pan
  • Leavening — Commercial yeast vs. sourdough behave differently, especially with whole grains
  • Formula (white) — 5–6× the pan volume in cubic inches (L×W×H)

Free-Form Loaves & Bannetons

Banneton size should match the total dough weight of your recipe.

Mini Boule—150 g
Bread Bowl—250 g
Small Boule or Batard—750 g
Regular Boule / Batard (sourdough)—900–1,000 g
Multigrain or Dense Boule—1,000–1,200 g
Round Banneton8"225–450 g

Round Banneton11.75"1,360–1,530 g
Home Oven Baguette—200–250 g
Standard Baguette—340 g
✦ What drives the range
  • Recipe — Free-form weights are primarily recipe-driven, not container-driven
  • Grain composition — Multigrain and whole grain loaves are denser and heavier at the same volume
  • Banneton sizing — The broad ranges reflect different dough densities; match the banneton to total recipe weight
  • Scoring — Free-form loaves rely on proper scoring for oven spring; dough weight alone doesn't guarantee loaf size

✦ What drives the range
  • Consistent sizing — Always weigh individual pieces; volume estimation leads to uneven baking
  • Recipe density — Enriched doughs expand more than lean doughs at the same dough weight
  • Desired finished size — Scale up or down by 10–15% to adjust; be consistent within a batch

Detroit 8"×10"—300–400 g
Detroit 10"×14"—500–600 g
✦ What drives the range
  • Crust style — Neapolitan is thin and blistered; NY has chew and foldability; thick/pan has a bread-like crumb
  • Hydration — Higher hydration doughs stretch more easily, so less dough reaches the same diameter
  • Rule of thumb — 1 oz (28 g) per inch of diameter for round pizzas up to 16"

10" Round PanØ 10"~300 g400–500 g550–650 g
Cast Iron SkilletØ 10–12"—400–600 g600–800 g
✦ What drives the range
  • Desired thickness — The dominant factor; thin focaccia uses roughly half the dough of a thick, pillowy version
  • Hydration — Focaccia is typically very high hydration (75–90%); higher hydration spreads further and rises more dramatically
  • Proofing — A longer cold proof produces more bubbles and lift, so a lighter piece can still fill the pan
  • Olive oil in pan — Generous oil creates a fry-like effect on the bottom and influences spreading to the edges
