Your hard-boiled egg looks gray because of a harmless chemical reaction between sulfur from the egg white and iron from the yolk, forming iron sulfide, usually caused by overcooking or high heat; the solution is to cool them quickly in ice water and avoid boiling for too long to prevent the unappealing greenish-gray ring from forming.

The egg float test is partially accurate: it reliably indicates an egg's age by measuring the size of its internal air cell, but it doesn't always signal spoilage; a floating egg is old and less fresh (better for baking), while a sinking egg is fresh, but a rotten egg might still sink, so the reliable method is always the sniff test (cracking it into a separate bowl) for true spoilage.

Eggs aren't refrigerated in Mexico because they aren't washed, leaving a natural protective outer layer (cuticle) intact that keeps bacteria out, making them safe at room temperature, unlike in the U.S. where washing removes this layer, necessitating refrigeration to prevent spoilage. Mexican eggs are sold unwashed and often locally, relying on this cuticle and a shorter supply chain for freshness.
