(HealthDay News) -- Hard-boiled eggs are a delectable treat, but make sure you prepare and store them properly.
The Academy of Nutrition and Dietetics advises:
- Cook hard-boiled eggs by bringing them to a boil, then cover and turn off heat and allow them to sit for 15 minutes. Then cool in a bowl of ice water.
- Never leave eggs out of the refrigerator for longer than two hours.
- Buy eggs before the sell-by date and use them within three-to-five weeks of purchase. Eat hard-boiled eggs within a week of boiling.
- If you see a green ring around the yolk after hard-boiling, the egg is OK to eat. It's just a sign that the egg was cooked a bit too long.
