When an avocado is soft and ripe, it’s usually easier to slice or dice it before removing its skin. Just before serving, cut the avocado in half lengthwise and remove the pit. Using a paring knife, cut the avocado diagonally into 1/4-inch (or wider) slices, without piercing through the skin. If dice is your goal, make a second set of diagonal slices perpendicular to the first. To remove the sliced or diced avocado from its skin, hold the avocado in the palm of your hand and, using a large spoon, carefully scoop out the slices.
