There are some differences between white duck and mackerel duck in terms of taste and cooking methods.

1. The meat of white duck is tender, and the soup flavor is clear and mellow, and there is no need to add any ingredients except salt when simmering, so the taste is not fishy and greasy.

2. Sesame duck, on the other hand, is marinated, which has certain nourishing and stomach nourishing effects.

Overall, white duck is superior in taste and the meat is more tender, while hemp duck has certain advantages in nourishing and stomach nourishing. However, it should be noted that individual tastes and preferences vary, and subjective evaluations will also vary.
