Step 1. Wash your avocado. Use a knife to make a lengthwise cut around the seed, cutting through the fruit and skin.
Step 2. Holding the avocado in your hands, gently twist the two halves in opposite directions to separate them.
Step 3. To remove the seed, use a quick, hard motion to whack the blade of the knife into the pit; twist and pull to remove it.
Step 4. On a cutting surface, cut each half in half again, and peel away the skin from each of the quarters using your fingers or a small knife. You can also cut slices in the avocado half, cutting through the fruit but not through the skin, and scoop out slices using a spoon.
