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.
To firm up at 100Â° it takes an additional 2 minutes (you can test this by dropping some egg yolk into boiling water in a freezer bag and observe, I just did that to verify my old numbers). So in this case you'll have 9 minutes for a hard boiled egg and around 5 for soft boiled. By then the time/temp equation has normalized and you'll see longer and longer spans between consistency changes. Custardy is about 5 minutes for a medium (Grade AA) egg. Secondly, my approach.
