What constellation is 12.9?

Eggs are usually boiled for 5- 10 minutes. Wash the eggs before you boil them, or they will get dirty. Boil in water until the water boils, and then cook for 5 minutes. Most of the egg whites are ripe, but the yolk is not ripe; Cook for 7 minutes, the egg white is cooked and the yolk is half cooked. This time is what we often say: sugar permeates eggs; Boil the egg white and yolk for 10 minute. Soak the boiled eggs in cold water and take them out. At this time, the taste is just right. Cooked for too long, the nutrients of eggs will be destroyed and the taste will get old.
