Have you ever tried to cut an onion into thin slices, and then the half moons end up being large, floppy, and hard to eat?

How to (safely!) remove the pit from an avocado

Another veggie that requires some technique when chopping is avocado! It’s especially important to practice safe techniques when removing the pit of an avocado. We have a great method for removing the pit, and safely releasing the pit from the end of the knife! Here’s how to cut an avocado:

Using a large chef’s knife, cut lengthwise around the avocado. Twist the two halves to separate them.
Place a towel in your hand and put the avocado on top. With a gentle but quick motion, tap the knife into the avocado pit.
Do not attempt to remove the avocado pit with your hand! Instead, pull the cutting board close to your body, then place the pit against the far edge of the cutting board and pull back to release it from the knife.
Use a large spoon to scoop out the avocado from the peel. Place the avocado with the cut side down, then cut it into slices. Turn the slices and cut crosswise to make diced avocado.
