For Rings: Make even vertical cuts from the top to the bottom, leaving the root intact.
For Diced Onions: Make vertical cuts and then slice horizontally, again leaving the root intact. This creates uniform pieces.
Finish Up: Once you reach the root, discard it. The onion pieces should be perfectly sliced.
Tips:
Keep your knife sharp for cleaner cuts.
Chill the onion in the fridge for 15-30 minutes before slicing to reduce tears.
This method helps you achieve consistent slices while minimizing mess and tears! Enjoy your cooking!
