First place the avocado onto a suitable cutting board. With an 8 inch chef’s knife or similar, score the avocado from the stem end all around the amount of the avocado. Cut in deep enough so you feel the blade’s edge touch the single, large seed. When you have circled the avocado, hold the avocado on your two hands and twist along the cutline. The avocado should divide into two halves. 1 half will include the large, brown seed.
Place the Avocado half with the seed onto the cutting board, seed up. Keep your fingers away from the avocado. Use your chef’s knife’s cutting edge, sharply hit a blow on the middle of the seed. Sink the blade to the seed. Then, holding the avocado half with one hand, gently twist the seed . The seed will come free from the avocado half.
Removing the Seed in the Knife
I remove the seed from the blade by gently pulling the seed out of the blade using the stainless steel edge of the sink. After washing the seed to remove any residual avocado flesh, I prepare the seed for rooting.
To make avocado pieces, take a butter knife’s dull back edge and score the avocado flesh at 1/4 inch intervals, cutting to the shell but not through it. With the back edge of the butter knife, run it around the inside of the shell, loosening the slices. The pieces should slip away from the shell and fall out onto a waiting plate.
And there you have it: a pitted avocado, sliced and ready for your use!
Starting an Avocado Seedling
I take an empty half liter plastic water bottle (I used an Arrowhead™ water bottle) and using a sharp razor knife, slit the bottle in half just above the flare in the center. I drilled four holes around the pointed end of the seed using my trusty electric hand drill and a 1/16 inch drill bit. After seating a toothpick firmly into each of the four holes, I suspend the seed in the bottom half of the plastic bottle. Then I put the seed in its starter container on a sunny windowsill. After the seedling has grown a stem about one foot tall, I transplant it to a soil-filled clay pot. And that is my new avocado tree, started from a seed.
