The best way to know if your eggs are done boiling is to follow the recommended boiling times based on your cooking method and desired consistency. For soft-boiled eggs, the yolk should be runny, while for medium-boiled eggs, the yolk should be slightly set but still creamy. Hard-boiled eggs will have a fully set yolk. You can also use a timer to ensure accuracy. If you are unsure, you can always test one egg by cutting it open to check the consistency before boiling the rest.

Yes, you can boil eggs straight from the fridge. However, it's important to note that cold eggs are more likely to crack when placed in boiling water. To minimize the risk of cracking, you can let the eggs sit at room temperature for a few minutes before boiling. Alternatively, you can place the eggs in cold water and then bring the water to a boil, which allows the eggs to heat up gradually and reduces the likelihood of cracking.

Peeling boiled eggs can sometimes be tricky, but there are a few tips to make it easier. First, use eggs that are a few days old, as they tend to peel more easily than fresh eggs. After boiling, immediately transfer the eggs to an ice water bath to cool them down quickly. This helps to separate the egg membrane from the shell. Once cooled, gently tap the egg on a hard surface to crack the shell, then roll it between your hands to loosen the shell. Start peeling from the wider end where there is usually an air pocket, making it easier to get under the shell.

A greenish ring around the yolk of a boiled egg is usually a result of overcooking. When eggs are boiled for too long, the sulfur in the egg white reacts with the iron in the yolk, forming a greenish compound called ferrous sulfide. While it may not look very appetizing, it is safe to eat. To avoid this, make sure to follow the recommended boiling times and immediately cool the eggs in an ice water bath after boiling to stop the cooking process.

Yes, you can reuse the water after boiling eggs. The water can be used for cooking other foods, such as pasta or vegetables, as it contains some nutrients from the eggs. However, if the water has any egg residue or if the eggs cracked during boiling, it is best to discard the water to avoid any potential contamination. If you plan to reuse the water, make sure to strain it to remove any bits of eggshell or residue.
