No pantry is complete without onions and you can add them to pretty much everything. But chances are, you've been chopping them wrong.

There really is a way to do it without crying and get the perfect dice, according to news.com.au.

THE SECRET TO A GOOD DICE

We all know that chopping onions can make you weep. That's because onions contain sulphur compounds, and when you cut into them molecules are released in the air that react with the water in your eyes to create sulfuric acid, which burns.

There are some easy ways to reduce this problem, like refrigerating the onion an hour before slicing, or popping it in some iced water for five minutes.

But the best way is to chop it as follows. The trick is not to cut the root, which releases the majority of the evil gas:

1. Cut onion in half lengthways.
2. Slice off the top (not the root).
3. Make parallel cuts from the end, being careful not to chop through the root.
Note: For a finer dice cut cross ways through the centre of the onion at this point.
4. Then turn onion 90 degrees to make cuts across onion.
