How to Choose The Best Onion Slicer- The Ultimate Buying Guide


Let’s face it- the worst thing about prepping an awesome meal is getting the onions ready. Not only does the process leave your hands smelly but can also be a very teary affair. However, you shouldn’t shy away from including this important ingredient into your meal due to its rather strenuous preparation procedure. By investing in a quality onion slicer you will say goodbye to watery eyes and smelly hands.

What makes you cry when peeling an onion?

Before giving you a few tips on how to choose the best onion slicer for your needs, let’s understand what makes your eyes watery as you peel these tasty ingredients. Once you cut into an onion, it releases a certain chemical, syn-propanethial-S-oxide, which then triggers the lachrymal glands in your eyes leading to production of tears. It’s a defense mechanism of some sorts.

Why Do You Need an Onion Slicer?

Other than making your onion slicing experience a less messy affair, onion cutters provide you with uniform and precise cuts quickly. Some come with a catch container that holds the onions as you slice keeping your kitchen counter clean and organized as you work. Some of the slicers also double up as vegetable slicers which provides you with a variety of uses helping you leave pleasant memories on anyone who tastes your meals.

How Do I Cut Onions without Shedding Tears?

Here are a few ways you can prevent your eyes from tearing up every time you cut an onion:

  • Use a very sharp knife or an onion slicer with sharp blades – Doing so helps to quickly slice into the onion without producing a lot of the tear causing enzyme.
  • Store the onion in the freezer for about fifteen minutes before slicing it – Doing so won’t affect the taste at all.
  • Slice the onion under water – while this tactic is difficult to do since the onion keeps sliding out of your hands, it works.
  • Slice the onion under a steam – You can do so as a kettle or cooking pot releases steam.
  • Soak the onion in water – This may not work well if you are slicing onion rings but will reduce watery eyes.

Conclusion

There’s no denying that having an onion slicer will greatly improve your cooking experience. We hope that this review has provided you with an idea of how to go about getting an ideal onion cutter. So, more tears and sighs as you chop that onion.
