How to Use Silk
To use it, just finely grate it and add it to your melted dark, semi-sweet, milk or white chocolate at 95 F. Yes, that is MUCH hotter than you are used to. Trust me. Stir it in, let it melt a couple minutes, and stir again. You are then ready to pour it up into your molds.
Silk is shelf stable and does not go bad as long as it does not melt. If it does melt it is still perfectly good cocoa butter, but can't be used to temper with any longer. Just store it cool and dry.
Fine print - it comes as small pieces, not grated as shown.
Cocoa Butter Silk is a precisely tempered form of cocoa butter. It’s stable, but like all chocolate ingredients, it appreciates calm, consistent conditions.
Storage Temperature:
Keep between 65–70°F (18–21°C) — cool room temperature, away from heat sources or sunlight. Never refrigerate or freeze; condensation can ruin the crystal structure that makes Silk work its magic.
Environment:
Store in a dry, odor-free space. Cocoa butter readily absorbs nearby smells (coffee, spices, solvents, etc.). Keep tightly sealed when not in use.
Shelf Life:
Silk is shelf stable and does not go bad as long as it does not melt. If it does melt it is still perfectly good cocoa butter, but can't be used to temper with any longer.
Handling Tips:
Avoid direct contact with moisture or steam.
Use clean, dry utensils when scooping.
Once melted for use, don’t overheat — keep below 94°F (34°C) to preserve its crystalline form.
