Answers

1. Examples: In salads, as a snack, in sandwiches, or as deviled eggs. 2. Steps: Fill a pot with water, add salt, bring to a boil, carefully place eggs in the water, boil for 10-15 minutes, then cool in cold water. 3. Salt helps the eggs cook more evenly and makes the shells easier to peel. 4. The proteins in the egg coagulate and become more solid due to denaturation caused by heat. 5. The green ring is caused by the reaction between sulfur in the egg white and iron in the yolk when overcooked. 6. The Maillard reaction is a chemical reaction between amino acids and sugars when food is cooked, leading to browning and flavor changes. 7. Overcooking makes the yolk hard and green, while undercooking leaves the yolk too runny. 8. Keep boiled eggs in a sealed container in the refrigerator and eat them within a few days. 9. Example: Slice boiled eggs and mix with mayonnaise, mustard, and herbs for a creamy egg salad.
