Rubber-band your sliced apple back together

For a lunch box, the best way to keep sliced apples from browning is to slice the apple, reassemble it, and wrap it in a rubber band. No soaking, no lemon taste, just physics.

Browning happens where the cut flesh meets oxygen. If you press the slices back into their original shape and hold them there with a rubber band, the cut surfaces are touching each other instead of the air. It works for the few hours between when you pack lunch and when your kid (or you) actually eats it. Throw it in an airtight container for extra insurance.

Lemon juice works too — the acid slows the enzyme that causes browning — but apples taste like lemons. If you want no weird flavor, a quick dip in honey water (2 tablespoons honey in a cup of water) does the same thing without the tang. The salt water trick works but leaves a salty residue unless you rinse and dry, which is a pain for a lunch box. If you’re packing in the morning and eating at noon, any of these will do. If you’re packing the night before, you’re fighting a losing battle; just cut them in the morning.

Don’t overthink it. Air is the enemy. Keep the cut surfaces away from it, and you’re done.

The rubber band trick is also a great way to peel the “I don’t like slices, I want a whole apple” argument off the table.
