Cantonese cuisine. Diced meat, strips of winter melon, bean nuts and sesame seeds are made into a filling, and the outside is wrapped with salted egg yolks in the shape of a shell, which is dipped in bread flour and deep-fried. The crunchiness of the flour, the mellow flavor of the egg yolk, the chewiness of the bean kernel, sesame, and diced meat, and the sweetness of the diced sweet winter melon make it look like a shell containing pearls, and it tastes crispy and delicious (transferred from the Internet)
