How to stop tears from coming out of your eyes while cutting onions
Easy Hacks to Peel One Kg Onion Fast: Chopping or peeling onions is one of those kitchen tasks that almost everyone faces. Whether cooking vegetables, making gravy, or preparing a special dish, onions are hard to do without. But the biggest problem with onions is their strong smell and the teary eyes they bring. Sometimes, just peeling or chopping a few onions can make your eyes water, making kitchen work difficult.
If you avoid preparing large quantities of onions at once, you won't need to. With a few simple kitchen tricks, you can prepare onions in less time and significantly reduce teary eyes. Especially when you have to peel up to 1 kilogram of onions, these little hacks can be very useful.
Why do my eyes water when I peel onions?
Onions contain sulfur compounds and enzymes located within various compartments of their cells. When the onion's cells break down during cutting or peeling, these compounds react, producing a gas. This gas reaches the eyes and causes irritation. To protect the eyes from this irritation, the body produces tears. This is why watery eyes may occur when cutting or preparing onions. However, this problem can be minimized by handling onions properly.
Easy way to prepare 1 kg onion in 2 minutes
If you have a large quantity of onions to peel, prepare them all at once instead of scrubbing each one for a long time. This will save you time and ensure a more organized task. First, loosen the dry outer layer of the onion slightly. Then, cut off the dry top layer. Be careful not to cut all the way to the root end, as this part contains the highest concentration of tear-inducing compounds.
If you need to cut an onion in half, cut it from the top toward the root, saving the root portion for the end. This method breaks down the onion cells less and can also reduce the effects of the gas that can irritate the eyes. If you only need to peel an onion, remove the outer layer and discard it immediately, then clean and store the entire onion together. This way, it's easier to prepare 1 kg of onions in batches.
The hack of cooling onions first will also work.
If your eyes water excessively while chopping onions, you can refrigerate them for about 30 minutes before using them. The cold temperature can help slow down the chemical reactions in the onion. Be careful not to leave the onion wet or exposed for too long. Simply refrigerating it for a short time before chopping may be enough.
A sharp knife will cause fewer tears.
Blunt kitchen knives can cause repeated pressure when cutting onions. This can break down the onion cells and release more eye-irritating compounds. Therefore, always use a sharp knife when cutting onions. A sharp knife produces a clean cut and requires less pressure.
How to Microwave Onions
Some people also use the microwave method to briefly heat onions before chopping them. Heating them briefly at a low temperature can kill some of the enzymes in the onion and reduce the burning sensation when cutting. However, this method may not always be suitable if the onion is being used in salads or other dishes that require a fresh flavor and crunch.
