Onions release syn-propanethial-S-oxide, a gas that irritates eyes. Beat the burn with these tricks:

**1. Chill First**: Refrigerate onions for 30 minutes or freeze for 10. Cold slows enzyme activity, reducing gas release.

**2. Sharp Knife**: A dull blade crushes cells, releasing more irritants. Use a honed chef’s knife for clean cuts.

**3. Water Works**: Cut onions under running water or submerge halves in a bowl while slicing. Water traps the gas.

**4. Ventilation**: Open a window or turn on a fan to disperse fumes.

**5. Mouthguard**: Chew gum or hold a wooden spoon between your teeth—this encourages breathing through the mouth, not the nose.

**Pro Tip**: Cut the root end last, as it contains the highest concentration of enzymes. For bulk prep, use a food processor with a lid.
