To slice your onion

• Cut a peeled onion in half.
• Place one half of the onion face down on to the chopping board and place your fingers at the edge.
• Tuck the tips of your fingertips, so that they are not exposed.  
• Begin slicing downwards with your knife.
• The side of the blade of the knife should slide off and away from your fingers preventing any injuries.
• The knife should slice through the onion all the way through.
• When you have sliced about ¾ of the onion turn the remaining piece of onion down and continue slicing.
• You should have nice, clean cut slices.
• Repeat with the other half.

To dice your onion

• Cut a peeled onion in half.
• Rotate so that the root is facing away from you.
• Don’t slice the onion all the way to the edge, leave some root joined.
• Rotate and star slice it again, creating little cubes.
• The knife should slice through the onion all the way through, until it makes contact with your chopping board.
• When you have reached the root which is joined turn it down and continue.
• You should have nice, clean cut cubes! A perfectly diced onion!
• Repeat with the other half.
