If you like your eggs hard-boiled, it's not a bad idea to keep lemons around. Before you drop the eggs into the boiling water, try brushing some lemon juice over the shells to prevent them from cracking while they cook. While you're at it, if you drop a teaspoon of lemon juice into the water, the eggs will be much easier to peel once you're ready to eat them. And don't worry about the juice affecting the eggs' taste -- as long as you don't go overboard, you shouldn't notice it at all.
Did You Know? Mixing a spoonful of lemon juice into boiling water will prevent rice from clumping up and sticking to the pot. A teaspoon of it will also keep boiling potatoes and cauliflower from turning brown.
