Medium-boiled: 7 to 9 minutes
Hard-boiled: 10 to 12 minutes
Spin the egg on a flat surface; a cooked egg spins smoothly and evenly
Stop the egg with your finger; a boiled egg stops quickly, a raw egg keeps wobbling
Remove the egg and crack it open to check the yolk and white
The white should be fully set and the yolk should be cooked to your desired firmness
