Why This Technique?
Tangzhong (a cooked flour-and-water roux) gives a softer, more stable crumb and extended freshness with the same hydration feel.
A tangzhong gelatinizes starches before they go into the dough, increasing water-binding capacity so the final loaf holds more moisture and stays softer longer. It also makes high-hydration doughs easier to handle because some water is bound in the gelatinized starch matrix rather than free in the dough [1][2].

When to Use
✓ Suitable for:
- • Enriched sourdoughs with milk, butter, or sugar (improves texture)
- • High-hydration wheat doughs where softness is desired
- • Sandwich loaves and rolls where extended freshness matters
✗ Not suitable for:
- • Lean, crust-forward artisan boules → Tangzhong softens crumb and reduces very crisp crust character
- • Pure rye breads → Rye relies on pentosans and benefits little from gelatinized wheat starch
Step by Step
Preparation:
Measure on a [kitchen scale](https://amzn.to/4pUMVHi). Prepare tangzhong in a small saucepan and cool before mixing with other dough ingredients.
Decide tangzhong ratio: common formula is 1 part flour : 5 parts water by weight (e.g., 20 g flour + 100 g water) for a 5% tangzhong in final dough; adjust to recipe.
Combine flour and water for tangzhong in a saucepan and whisk until smooth. Heat over medium-low while stirring continuously.
When the mixture reaches about 65–70°C and thickens to a paste (ladle-coating), remove from heat and cool to room temperature or fridge to speed process; cover with plastic to prevent skin.
Add the cooled tangzhong to your dough formula during mixing (with other liquids). Mix until combined; proceed with autolyse if your formula includes one.
Bulk ferment, shape, and bake as usual. Expect slightly more open and moist crumb; adjust proof times as tangzhong can speed fermentation slightly.

How Often?
Use tangzhong in any loaf where you want improved softness and moisture retention; common in enriched loaves or sandwich breads.
How do I know it's enough?
Loaf crumb is moist and tender without gummy texture; dough handles easily and final loaf keeps softness for several days compared to non-tangzhong control [1].
Common Mistakes
❌ Using tangzhong too hot
Problem: Hot tangzhong can kill starter activity or shock water temperature control
Solution: Cool tangzhong to room temperature (or at least under 40°C) before mixing with starter and yeast
❌ Adding too much tangzhong
Problem: Can create gummy crumb and overly tight texture
Solution: Stay within 3–10% of total flour weight and test gradually
❌ Not accounting for bound water
Problem: Blindly maintaining original dough water can make dough too slack if tangzhong is large
Solution: Adjust total dough water with awareness that tangzhong binds water; start with recipe guidance and tweak hydration by feel
