Remove the pit: Give the avocado a vertical slice and remove the pit
Slice the avocado inside the skin: Using just the tip of the knife, slice into the avocado flesh, making sure to not pierce the skin. Follow the natural curve of the avocado using the tip of the knife. Repeat until you have cut through the entire avocado. Slices can be as thick or as thin as needed and can go either vertically or horizontally. You can also slice the avocado in both directions, cross-hatched, to make cubes.
Scoop out the avocado: Gently work a spoon between the flesh and the skin of the avocado. Following the curve of the avocado with the bowl of the spoon, scoop the slices out of the shell.
