If you use boiled duck eggs, it will take about eight minutes to cook them. If it takes more than eight minutes, the nutritional value of the duck eggs will be lost to some extent, but the cooking time should not be less than six minutes, because the duck eggs are probably not cooked until six minutes, so there may be some bacteria in the duck eggs, which will do harm to the human body. If duck eggs are boiled in cold water, it needs to be boiled for 15 minutes, because it needs to be boiled in cold water first, which also takes a certain process.

When cooking duck eggs, it is best to cook them in cold water, because duck eggs cooked in cold water are not allowed to explode. As the water temperature rises, duck eggs will slowly expand from the inside out. When the water temperature reaches a sufficient temperature, the protein will solidify and the duck egg shell will almost expand, so that the duck egg shell will not be broken due to external expansion. Before boiling duck eggs, you must clean them, and you must buy fresh duck eggs, such as cracked or smelly duck eggs, which means that they are not fresh and can no longer be eaten. Some bacteria will remain in the shell of duck eggs, which will cause certain harm to human body if these bacteria are not cleaned.
