Pro Tip

To create a firm grip for the cutting board, cut the tissue paper, which goes straight on the table, and splash some water on the tissue paper. Then, place the chopping board on that wet tissue paper. It will create a grip for the chopping board and will not move very easily.

To hold an onion on the table, you need to make a firm grip by placing your thumb on one side and index and middle fingers on other side. Then, through that arch, slide your knife carefully and press it against the chopping board. 

After that, you will get two parts of an onion.

  • Now, remove the caps from both sides as small as possible.
  • Peel off the skin of the onion.
  • It’s time to pour the onions under a bowl of water.

Why You Need to Pour Your Onions Under Water

  • Sometimes, there is a black powdery coating over onions, which would possibly be fungus.
  • Onions naturally have sulfur in them, making our eyes watery. Hence, cutting and soaking them in water can actually remove the sulfur from onions.

Cut at least 3-4 onions before we start chopping.

Now, rub the onions under water to remove the fungal activities.

Different Types of Cutting

Let’s see different ways to cut an onion.

Vertical Slicing

Now gradually and evenly make the fine cuts, which can be as fine as possible. Keep sliding your fingers backward when the knife keeps approaching. If you notice the motion of your knife, you’ll understand it more clearly. 

Tip

  • To make perfect cuts, it is necessary to have a sharp knife.
  • When you reach the ends, push it down, and start chopping it, like before.
  • Do not concentrate on speed; it comes with practice. At this stage, focusing on the precision and accuracy of cutting onions is essential.

Again the grip remains the same. The thickness and the thinness of the onions depend on you entirely.
