Method of Preparation:
1. Grip the avocado gently on one side with one hand. With a large, sharp knife in the other hand, cut the avocado lengthwise around the seed. Open the two halves to expose the pit.
2. For safety, fold up a kitchen towel and use that to hold the avocado half with the pit. Gently tap the pit with a knife with enough force so that the knife edge wedges into the pit, but not so hard as to cut all the way through it. Tap it very gently a few times, each with increasing pressure, until a cut is made in the pit sufficiently to twist the pit out.
3. At this point, you can either scoop out the avocado flesh with a spoon (for making guacamole), or slice the avocado into segments.
4. To make avocado slices, use a knife to slice the inside of the avocado halves into sections. Don't worry if you cut right through the peel.
