　　The quality of shark fins is mainly assessed based on their species and body part. In terms of species, Tiānjiǔ fins are top-tier, Hǎihǔ and Jīngōu fins are mid-tier, and Huángjiāo, Yáchǐ, and Qīngpiàn fins are common-grade. Regarding body parts, the dorsal fin is the highest quality, followed by the tail fin, and the chest fin is the lowest. Beyond these two criteria, the origin of the fins, their color depth, and the size of the fin slices also affect their quality.

　　The preparation (soaking and softening) of shark fins is relatively complex. There are roughly three methods for softening shark fins: alkaline soaking, steaming, and simmering. Fins softened using alkali yield the poorest results—the resulting dish may have a slight alkaline taste, poor texture, and significant shrinkage under high heat, losing their shape. Steaming takes a long time and does not easily remove the fishy odor. Simmering, however, requires less time, effectively removes the fishy smell, and yields better texture. Therefore, the simmering method is now commonly used for softening shark fins.

　　1. Simmering Method: Rinse the shark fins with clean water to remove any dirt or fuzz, trim the edges, then soak them in water at 40°C. Change the warm water every 8 hours or so, keeping the fins soaked for 24–30 hours until they have fully absorbed the moisture. Remove the fins and place them on a piece of bamboo mat, cover with another bamboo mat, and secure the two mats together with bamboo skewers to hold the fins firmly in place. Fill a stainless steel pot with purified water, add the secured fins, bring the water to a boil, then reduce the heat to low and simmer for 5–6 hours until the cartilage separates from the softened meat. Take out the fins, rinse them in cold water, remove the bamboo skewers and mats, then rinse again to eliminate any fishy smell. During the rinsing process, gently remove any small cartilage pieces, and repeatedly wash away any broken cartilage or sand caused by simmering. If any meat residue or debris remains, use a bamboo stick to carefully pick it out. At this point, the shark fins are ready for use.

　　Note: Do not break apart the fins; instead, keep them neat and intact.

　　　2. Technical Points:

　　1. Be mindful when selecting your fins—regardless of grade, never use moldy or spoiled shark fins.

　　2. When soaking, be sure to change the warm water frequently—at least 3 times—to prevent spoilage due to foul-smelling water.

　　3. Before simmering, secure the fins tightly between two bamboo mats. This prevents the fins from sticking to the bottom of the pot and also avoids deformation or disintegration.

　　4. Pay attention to the simmering time. Based on experience, older, tougher fins typically require 5–6 hours, while softer, more tender fins need about 4–5 hours. Do not simmer for too long—over-soaking can cause the surface to crack and trap sand. That said, the time should not be too short either, or the black outer membrane and grit won’t be fully removed.

　　5. Use low heat throughout the simmering process—do not let the water boil vigorously. High heat may cause the surface to break, making it susceptible to rotting, sand infiltration, and difficulty in removing the skin and grit. Also, sort the fins by size and tenderness before softening, and simmer them separately; otherwise, the smaller, more tender fins may overcook while the tougher, larger ones remain under-softened.

　　6. Do not use iron or copper pots when simmering shark fins. Shark fins contain sulfur-containing proteins that react with iron and copper, producing compounds like iron sulfide that create black or yellow spots, compromising the appearance of the finished dish. It is recommended to use ceramic or stainless steel cookware.

　　7. Throughout the simmering process—and after the fins are softened—avoid contact with oil, alkali, salt, or similar substances, as they can dissolve the fin’s outer layer and ruin the dish’s quality.

　　8. When removing meat residue and bone fragments from the softened fins, use a bamboo stick to gently lift and clean them, maintaining the fins’ neatness to preserve the visual appeal of the final dish.

　　9. After removing bones and grit, rinse the fins repeatedly with clean water and continuously flush them. This serves both to clear away any remaining bone or grit and to fully eliminate the fishy odor.
