Boiling Eggs

Most of my family members love to eat eggs, especially half boiled eggs. Yesterday, me and whoisbaby was discussing how to prevent the egg's shell from cracking when boiling. Finally I found out how to prevent the egg's shell from cracking from the The Egg Cookbook.

Boiling Eggs:

1. Prevent shells from cracking. Allow refrigerated eggs to thaw before putting them in boiling water. Adding eggs to cold water then bringing to a boil together also helps to prevent the shells from cracking.
2. Seal cracks in shells. Add a little vinegar or salt to the water. This helps the whites to set faster, which effectively seals the cracks, if any, and prevent more whites from seeping out.
3. Centre yolks. When boiling eggs, keep stirring the water to keep the eggs moving. Stirring positions the yolk in the centre, which is aesthetically more pleasing than lopsided egg yolks.
4. Tender soft-boiled eggs with runny yolks. Put the eggs into cold water then bring to a boil over moderate heat. Turn off the heat, leave the eggs to steep for 5 minutes then rinse quickly with cold water.
5. Easy shelling. Wait for hard-boiled eggs to cool completely before shelling them. Cracking the shells and then soaking the eggs in tap water helps to loosen the shells, making them easier to shell.
