Another thing about avocados: don’t remove the pit unless you are eating the whole avocado at one time. The pit keeps the unused portion from browning.
When cutting an avocado. hold it so the pointy end is up; put the knife blade in there, and slice to the bottom. If you are using a half or whole avocado, continue cutting on the longitudinal axis until you have circumnavigated the whole avocado.
Grab the two halves with different hands and begin to twist; the halves will separate with one holding the pit.
If you are only wanting a smaller portion of the avocado. make two slices along longitudes from one end to the other, and remove the wedge of avocado ready to use!.
