How can you choose fresh eggs without breaking them? You can use your eyes, ears, and nose. First, look at the shell. A fresh, good-quality egg usually has a bright, unbroken shell with a slightly rough surface. Be careful with eggs that have cracks. Do not use eggs with strange patches that look like mold.
Next, shake the egg gently in your hand. A fresh egg feels solid and makes almost no sound. In an older egg, you can feel the inside moving. Then smell the shell. Fresh eggs usually have no strange smell. Do not eat an egg with a sour or rotten smell. Finally, buy eggs from stores you trust and check where they come from.
