Hold the avocado firmly in one hand and cut lengthwise until you feel the pit. Rotate the avocado in your hand while holding the knife steady to cut it in half.
Hold the avocado in both hands and twist to separate the halves.
Tap your knife (carefully) into the pit of the avocado. Turn it like you're turning a key to loosen and remove it from the avocado.Carefully knock the pit off of the knife using the back of a spoon or pop it off with the edge of a thick cutting board - do not attempt to remove it with your bare hand.
Hold the avocado half in one hand. Score the inside of the avocado lengthwise with your knife. Run the knife through to reach, but not pierce, the skin. Slice as thinly or thickly as you prefer.To cut into dice, run the knife in the opposite direction after cutting your slices.
After slicing or dicing your avocado, peel it by taking a spoon and running it under the flesh of the avocado. This will loosen it from the peel and make it easy to remove in one piece.

Notes
You can tell an avocado is ripe if it's dark in color and is slightly soft when gently squeezed. If it is firm, bright green, and will not yield to pressure, it is not yet ripe.
To immediately ripen your avocados, bake them wrapped in foil at 200°F for 10 minutes or until they are soft to the touch.
To ripen quickly over 2 to 4 days (depending on how ripe they are to begin with) store in a brown paper bag on the kitchen counter.
