Scalds

Scalds are a texture control move: pre-gelatinize flour with hot water before final mixing. They are how you steer crumb softness, chew, and moisture retention with intent instead of guesswork.

Best ForChoosing a scald method when softness, chew, or shelf life needs to change.

IMPORTANT

Always let scalds cool before they touch yeast. Hot scald can damage yeast activity and weaken fermentation.

In the KitchenRatio calculator, scalds live in Advanced → Scalds.

Types in the Calculator

• Tangzhong
  Cooked flour paste built for softness and shelf life.
• Yudane
  Boiling-water scald that pushes chew and moisture retention.
• Scandinavian scald Hot rye or whole-grain scald for grain hydration, keeping quality, and traditional pan or hearth loaves.

NOTE

The calculator allows only one scald type at a time: tangzhong, yudane, or Scandinavian scald.

Quick Choice

• Choose tangzhong when you want a softer, more pillowy crumb and longer-lasting tenderness.
• Choose yudane when you want more chew, more wheat presence, and stronger moisture retention.
• Choose Scandinavian scald when rye or whole-grain behavior is the real problem you are trying to solve.

Traditional European / Scandinavian Scald

This style is common in rye-heavy and mixed-grain baking, where hot water is used to hydrate and soften part of the flour (or meal) before final mixing. It is less about "pillowy milk bread" and more about flavor development, moisture control, and crumb stability in hearty loaves.

How it behaves:

• Hot water hydrates starches and changes how flour absorbs and holds water.
• Often improves keeping quality and can support a more even crumb in dense dough systems.
• Can also mellow sharp grain notes and build a deeper malt-like profile.

Typical use in practice:

• Frequently used with rye flour, whole grain flour, or coarse meal components.
• Can be made with plain hot water or paired with malt/syrup in some regional styles.
• Usually prepared ahead of final mixing and cooled before yeast is introduced.

Deeper Breakdown

Tangzhong

• Typically uses a higher water ratio and is heated into a smooth paste.
• It helps dough stay soft and tender longer.
• It often works best in sandwich loaves, rolls, and milk breads.
• Push it too hard and dough can go gummy or too soft.

Yudane

• Usually built at lower water ratio with boiling water and rested.
• It adds chew and usually tightens dough feel versus tangzhong.
• It is useful when you want structure plus moisture retention.
• If under-rested or under-hydrated, it stays lumpy and fights your mix.

Scandinavian Scald

• Often used with rye flour, whole grain flour, or coarse meal.
• Focuses on grain hydration behavior, moisture retention, and flavor depth in robust loaves.
• Usually less about ultra-soft crumb and more about stability and keeping quality.
• Works best when cooled fully before yeast enters the system.

How Allocation Works

Like preferments, scald flour and water are allocated from your existing formula. They are not extra add-ons.

• Scald flour grams = total flour × flour allocation %
• Scald water grams = scald flour × water ratio

You get live totals for:

• allocated flour and water
• remaining main dough flour and water

Tangzhong Settings

• Flour allocation: 0 to 20% (default 5%)
• Water ratio: 1.0 to 8.0 (default 1:5.0 flour:water)

Yudane Settings

• Flour allocation: 0 to 25% (default 10%)
• Water ratio: 0.8 to 1.5 (default 1:1.0 flour:water)

Scandinavian Scald Settings

• Best used with rye flour or whole-grain flour allocations
• Built with boiling water poured over the allocated flour
• Usually cooled fully or to warm before final mixing
• Most useful when flavor, grain softening, and moisture retention matter more than an ultra-soft crumb

How to Make Tangzhong

1. Weigh flour and water using your target flour allocation and ratio.
2. Whisk together in a saucepan until no dry flour remains.
3. Heat over medium-low while stirring continuously.
4. Cook until it thickens into a smooth paste.
5. Remove from heat, cover surface, and cool before mixing final dough.

Typical target texture:

• Thick pudding-like paste that holds brief lines from the whisk.

Typical use:

• Mix fully cooled tangzhong into the final dough with the remaining ingredients.

How to Make Yudane

1. Weigh flour and boiling water at your target ratio (often near 1:1).
2. Pour boiling water over flour and mix until evenly hydrated.
3. Cover and let it rest until fully cool and hydrated through.
4. Optionally refrigerate overnight for easier handling.
5. Tear into pieces and mix into final dough.

Typical target texture:

• Firm, hydrated mass with no dry pockets.

Typical use:

• Works well when added in chunks during initial mixing.

How to Make Scandinavian Scald

1. Weigh the flour and water shown in the calculator for the scald allocation.
2. Bring the scald water to a boil.
3. Pour the boiling water over the flour and mix until evenly hydrated.
4. Cover and let it cool until warm or fully cool before adding yeast.
5. Mix the scald into the final dough with the remaining ingredients.

Typical target texture:

• Thick paste or heavy mash with no dry flour pockets.

Typical use:

• Especially useful in rye breads, mixed-grain pan loaves, and breads where improved keeping quality matters.

Practical Workflow

1. Build your base formula in the calculator.
2. Open Advanced → Scalds.
3. Enable tangzhong, yudane, or Scandinavian scald.
4. Set flour allocation and water ratio.
5. Prepare the scald using the displayed flour and water grams.
6. Mix final dough using remaining flour and water shown in Advanced.

Practical Tips

• Start with tangzhong around 5% flour and 1:5 ratio for softer sandwich-style crumbs.
• Start with yudane around 10% flour and 1:1 ratio for chewier texture.
• For Scandinavian or rye-style scalds, start modest and observe dough behavior before increasing scalded flour share.
• If dough feels tighter than expected, review Hydration and adjust on purpose.
• Keep total advanced allocation in range to avoid over-allocation warnings.

Troubleshooting

• Crumb feels gummy
  • Lower scald flour allocation.
  • Confirm bake is fully done before cooling.
• Dough feels too tight
  • Reduce yudane allocation or raise final dough hydration slightly.
  • Increase rest time after mixing before shaping.
• Scald does not blend smoothly
  • Break up lumps before final mixing.
  • Let the scald cool fully and hydrate evenly.
