How is crimson silk processed?
"Blue silk" is actually a type of candied fruit made from sweet orange peel, not a fabric. It has a dry surface and a sandy texture, making it a traditional dried sugar product.
The process begins with fresh orange peels. First, the peels are cut into thin strips, about 2 to 3 mm in width. They are then soaked in water and heated repeatedly, with the water changed multiple times to remove the bitterness. Once the bitterness is gone, the peels are drained and ready for the next step.
Next comes the sugar cooking stage. Typically, 50 kg of raw sugar is used along with 40 kg of white sugar. A small amount of water is added to create a thick syrup, which is then mixed with the prepared orange peels and heated. At the beginning, high heat is applied to quickly evaporate the moisture from the peels while allowing the sugar to penetrate. The mixture is continuously stirred as it cooks. Over time, the peels become translucent.
When the sugar starts to crystallize and return to sand, the coloring process begins. Since the original peel is white, it can be dyed red or green. Red is achieved using food-grade red coloring, while green uses copper sodium chlorophyll. The dye is dissolved in a small amount of water and then mixed into the sugar. As the syrup approaches the point of recrystallization, the temperature must be carefully controlled to avoid burning or caramelization, which could result in a dark brown color—making the product unsellable. The final product should have fine, even sugar crystals.
After cooking, the product is transferred to a drying room and dried at around 60°C until the moisture content reaches 16–18%. This ensures the product remains crisp and long-lasting.
Finally, the finished product is packaged. It comes in red, green, or orange colors, offering a purely sweet flavor with a sugar content of 70–75%. It retains the distinct aroma of orange peel and is commonly used as a filling for buns or cakes. However, eating it directly may be too sweet due to its high sugar content.
