Here’s the way to cut an avocado. I’ve been using this method for 40 years and have never suffered so much as a scratch. First, take a small paring knife and slice into the avocado at the top, the smaller end, down to the nut. Then, move the knife around to the bottom of the avocado and then back to the top, keeping the knife in contact with the nut. Next rotate the avocado 90 degrees and make the same cut, from the top to the bottom and back up again. Now, starting that the smaller end, take the point of the avocado’s skin and peal it back to the bottom to remove it. Repeat this with the other three quarters. Finally, starting at the middle of the avocado, peal the quarters apart from the nut. They will come off cleanly and easily.
That’s what I do....2 cuts and a wiggle.
