When is a baby officially considered premature? Q: When is a baby officially considered premature? A: Although pregnancy is generally 40 weeks long, babies born at 37 weeks are considered full-term (at that point, they're developed enough that they shouldn't have any age-related health issues).
If serving eggs cold, add 1 tray of ice cubes to a large bowl and fill with water. 2. Add 1 inch of water to a large pot. Place steamer insert inside, cover, and bring to a boil over high heat. Add eggs to steamer basket, cover, and continue cooking, 6 minutes for soft-boiled eggs or 12 minutes for hard-boiled. 3. Serve immediately if serving hot. If serving cold, immediately place eggs in a bowl of ice water and allow to cool for at least 15 minutes before peeling under cool running water.
This is where your timing needs to be precise. If the eggs sit in the hot water too long, they will overcook and end up with a green yolk. Extra large eggs will need 18 minutes to fully cook, large eggs need 15 minutes, and medium eggs need 12 minutes. Set a timer to prevent over or under cooking. For soft-boiled eggs (runny yolks, solid whites), let the eggs sit for 5 minutes less than the time needed to hard...MORE cook the egg.
