Why This Technique?
A hot-scalded flour paste (kochstück) increases water absorption, softens crumb, slows staling and allows higher dough hydration without slackness.
Kochstück (similar to tangzhong/scalded flour) gelatinizes starches so they bind more water and form a viscous network. That retained water stays in the crumb during baking and storage, improving softness and shelf life while permitting higher final dough hydration without excessive stickiness.[1][2][1]

When to Use
✓ Suitable for:
- • Breads where a soft, tender crumb is desired (sandwich loaves, enriched doughs)
- • High hydration sourdoughs where you want structure but less stickiness
- • Formulas with significant whole-grain flour to compensate for increased absorption
✗ Not suitable for:
- • Very lean, open-crumb artisan boules where crisp crust and very large oven spring are priority → Kochstück can slightly reduce crust crispness and the most extreme open-crumb characteristics
- • 100% rye breads → Rye starches behave differently; scalding is used in rye baking but as a different technique—follow rye-specific recipes
Step by Step
Preparation:
Weigh all ingredients on a [kitchen scale](https://amzn.to/4pUMVHi). Use a [dough whisk](https://amzn.to/4qGy5p0) or small whisk to prevent lumps. Cool the kochstück in a [large mixing bowl](https://amzn.to/45rc1Gk).
Decide ratio: common kochstück is 1 part flour : 5 parts water by weight (20% roux relative to flour weight). For stronger effect use 1:3 to 1:4; for milder 1:6.
Mix flour and cold water in a small saucepan until lump-free using a dough whisk.
Heat gently while stirring constantly. Temperature will rise and the mixture will thicken and become translucent; stop at about 65–70°C (149–158°F) or when it forms a pudding-like paste. Avoid burning.
Transfer to a large mixing bowl and cool to room temperature. Cover to prevent skinning.
Incorporate into the dough during initial mixing or autolyse: reduce the formula water by the water used in the kochstück (the kochstück water counts toward total dough hydration). Mix until homogenous.

Common Mistakes
❌ Not adjusting total hydration
Problem: You double count water and end up with overly slack dough
Solution: Always subtract the kochstück water from the main dough water; weigh carefully on a [kitchen scale](https://amzn.to/4pUMVHi).
❌ Overcooking (burning) the paste
Problem: Burnt flavor and degraded starch function
Solution: Stir constantly, use moderate heat and stop when paste is smooth and pudding-like.
❌ Adding while hot
Problem: Kills starter activity or accelerates fermentation unpredictably
Solution: Cool the kochstück to room temperature before mixing with starter and flour.
❌ Using too high a ratio for delicate breads
Problem: Excessive tenderness and weaker crust
Solution: Start with a mild ratio (1:5) and test before raising to 1:3–1:4.
Alternative Techniques
Tangzhong
Essentially the same method popular in Asian baking; use the same ratios and steps
Soaker (kochstück cold)
Mix flour and cold water and let hydrate without heat; increases absorption but lacks gelatinization benefits
High-temperature scald for rye
Rye baking uses scalded rye differently; follow rye-specific recipes rather than wheat kochstück
