Don't use the egg keeper in the door of the fridge. The eggs get bumped around and the temperature of the door fluctuates and can affect the freshness of your eggs. The best way to store eggs is in an airtight container in the coolest part, which is the back of the fridge.
Another important factor to keep in mind when storing eggs is that eggshells are very porous and can absorb the other flavours/odours of the fridge. Keep your eggs away from cut onions, and just to be safe, keep some baking soda beside your eggs to avoid any other sneaky odours stinking up your eggs.
Problem # 2: How to tell if an egg is hard-boiled
If you like to cook hard-boiled eggs to enjoy in your lunches, salads or sandwiches, you have to make sure you don't mistake your hard-boiled eggs for your fresh eggs if they get mixed up in your fridge.
The best way to determine whether your egg is hard-boiled or raw is to do the 'spin test'. Spin your egg on the counter and if your egg spins slowly and is a bit wobbly, it is raw. If your egg spins quickly, it is hard-boiled.
Problem # 3: Separating yolk from white
Making sure your egg white is separate from your egg yolk is very important for baking and especially for custards. It's also great if you are watching your cholesterol and want to make an egg-white omelette.
Using a small funnel makes separating an egg quick and easy. Crack an egg (room temperature is best) into a small funnel sitting over a glass; the egg white goes right through and the egg yolk sits nicely in the funnel.
Problem # 4: Tiny eggshells in your eggs
This happens to everyone at some point, so hopefully this little tip should be able to help save you from getting egg white grit in your morning pancakes.
When you crack an egg and some smaller pieces of shell get left behind, just use the larger piece of shell to scoop it out. The larger piece of the shell acts like a magnet and attracts the little pieces to it.
Problem # 5: Slicing hard boiled eggs without knife
If your kids are helping you make dinner, but you don't want them to use sharp knives, try this little trick for slicing eggs. Take a piece of dental floss and wrap it so that it is taught around your index fingers. You can slice right through the egg with perfect slices and without any danger from sharp knives.
This also works great if you're out camping or on a picnic. Just remember, don't use mint or any other flavoured floss!
