Boiled fertilized duck eggs are a popular snack throughout Southeast Asia. We’d describe the flavor as cross between the chicken and the egg. The duck is fertilized between 15-18 days and, when the time is right, boiled for 20 minutes. To eat it, crack the shell and scoop out the embryo (tiny beak, feathers and all), adding a pinch of salt and a squeeze of lime. The juice from within is quite a delicacy too. We spotted this child eating some as a snack.
