FAQ
How to cut onions without crying?

- Cut under running water or submerge the onion in water while cutting. This prevents the enzymes from reaching your eyes.
- Light a candle near your cutting board. The flame attracts the enzymes away from your eyes.
- Wear swimming goggles while cutting to create a barrier between your eyes and the onions.
