The Nusantara Spiced Salted Egg product is formulated with careful attention to quality and the authenticity of its ingredients to produce a distinctive taste, high hygiene standards, and strong market value. The main ingredients used include: 1. ​Fresh Duck Eggs: Selected from the best quality and meticulously sorted to ensure the shells are free from cracks and capable of absorbing the spices and herbs perfectly. 2. Coarse Salt: Acts as the primary osmotic agent, providing a savory salty taste while naturally preserving the eggs. 3. Clean Water and Bottled Vinegar: Vinegar is added to the soaking medium to help soften and open the pores of the eggshells, thereby accelerating the penetration of salt ions and herbal extracts into the egg to the maximum extent. (Note: Water and vinegar were repeated in the original text, but integrated here for clarity). 4. Natural Nusantara Spices: Utilizes a selected combination of star anise, cloves, lemongrass, and bay leaves. All of these spices are boiled together with the salt solution to release their aromatic extracts, which provide a distinct fragrance and eliminate the gamey odor of the duck eggs. 5. Clean Water and Bottled Vinegar: (As noted above) The vinegar solution helps open the pores of the eggshell so that the absorption of salt and spices is faster and more optimal.
