Delicious dishes made from ca chach
Ca chach braised with sedge leaf is a delicacy of gourmets. But an even more “exquisite” dish is ca chach cooked with ginger leaves. Clean the fish, wash it thoroughly, and put it in boiling water. When the fish is cooked, add finely chopped young ginger leaves. Equally delicious is ca chach braised with turmeric.

In the same family as ca chach, but larger, is chach lau (Mastacembelus armatus). Chach lau can be processed into many delicious dishes, but the “special trick” is grilling. Remove the fish’s internal organs, wash it thoroughly, and place it on a hot charcoal stove, turning it evenly until the fish is cooked.
The second grilling method is to place the fish on a hot coal stove to remove excess water, then bury the fish in hot ash until it is cooked, direct grilling. Both dishes are served with salted chili and buffalo horn chili. It is worth noting that when grilling, the fish should not be cut into pieces, even if the fish is large, as this will cause the fish to lose its characteristic flavor. However, there is still a more attractive grilling method. Choose live ca chach, scrape off the slimy layer on the skin, use a knife to slit the cucumber from top to bottom, stuff the fish into the cucumber tightly, then wrap it tightly with wire to keep the cucumber intact without cracking when grilling.
Use two fresh bamboo branches to stick into the ends of the cucumber, place it over a red hot charcoal stove, the cucumber’s sweet juice will seep into the fish. Use chopsticks to separate, pick up a piece of white fish meat, skillfully wrap it with raw vegetables, cucumber, and spicy green and red chili in a rice paper, then dip it in a bowl of sweet and savory tamarind fish sauce before eating. This dish will make your taste buds blissful!
For the dish “chach lau cooked with la giang leaves,” the fish must be cut into pieces, fried until golden before adding water to cook.
