If your cocoa butter silk has completely hardened, it does not mean it is unusable. Fully solidified silk still contains stable β-crystals and can be used for pre-crystallization after mechanical grinding.

The key is to use it correctly: grind it finely, add it at the right temperature, and adjust the dosage compared with liquid silk.

Why Cocoa Butter Silk Solidifies

Cocoa butter silk is a concentrated mass of stable cocoa butter β-crystals. When the incubator maintains the correct temperature, silk remains soft and workable. If the temperature drops or is not stable enough, the silk may fully solidify.

This does not destroy its function. Stable β-crystals remain structurally intact until cocoa butter is heated above their melting range. In practice, hardened silk is simply a solid mass of stable cocoa butter crystals.

Can Hardened Silk Still Be Used?

Yes. Fully solidified silk remains functional as a crystallization seed. It can still be used to pre-crystallize chocolate, praline fillings, nut pastes, spreads, and other fat-based masses.

However, dry silk behaves differently from liquid silk. It dissolves more slowly, distributes through the mass less easily, and requires a different working temperature and dosage.

How to Use Solidified Silk

If you do not have time to re-liquefy the silk, grate it on a fine grater until you obtain a fine powder.

Functionally, finely grated silk can be used similarly to cocoa butter powder products such as Mycryo. The purpose is the same: to introduce stable β-crystals into the product and start controlled pre-crystallization.

Recommended Temperature and Dosage

Dry silk should be added at a slightly higher product temperature than liquid silk. This helps the solid fat particles dissolve and distribute more evenly.

We recommend adding dry silk when the product is approximately 34°C. A temperature of 34.4°C is still acceptable, but temperatures approaching 35°C may melt a significant portion of the stable β-crystals and reduce the effectiveness of pre-crystallization.

Also keep in mind that dry silk is usually at room temperature, around 18–22°C. Once added, it may slightly lower the temperature of the product.

Why Dry Silk Requires 1%

Use approximately 1% dry silk instead of the typical 0.4% liquid silk dosage. At temperatures around 34°C, part of the crystal structure may partially melt due to normal temperature fluctuations and measurement tolerances.

Dry silk also takes longer to dissolve because each particle remains a solid fat crystal. A higher dosage compensates for this and helps ensure reliable pre-crystallization.

How to Calculate 1%

To calculate the amount of dry silk, convert the product weight to grams and divide by 100.

For example, if you need to temper 2 kg of product:

2,000 g ÷ 100 = 20 g

This means you should add 20 g of finely grated dry silk.

Common Mistakes When Using Dry Silk

• Adding dry silk to a product that is too cold, where it cannot dissolve properly.
• Adding it above 35°C, where stable β-crystals may begin to melt.
• Using the same 0.4% dosage as liquid silk.
• Not grinding the solid silk finely enough.
• Mixing too briefly, which prevents even crystal distribution.

FAQ

Can hardened silk still temper chocolate?

Yes. Hardened silk still contains stable β-crystals and can be used after fine grinding.

What temperature should the product be before adding dry silk?

The recommended product temperature is approximately 34°C. Avoid going close to or above 35°C.

Can dry silk replace liquid silk?

Yes, but the dosage should be increased to about 1%, and the product temperature should be adjusted accordingly.

Why does dry silk dissolve more slowly?

Dry silk consists of solid fat particles. These particles need more time and mixing to dissolve and distribute evenly throughout the mass.

How to Prevent Silk from Solidifying

The best solution is to maintain silk at a stable working temperature. A dedicated incubator helps preserve the correct consistency and crystal structure over time.

The Kadzama incubator is designed specifically for this purpose. It keeps cocoa butter silk stable, workable, and ready for reliable pre-crystallization without repeated melting, grinding, or temperature correction.
