Cheap plastic ice trays can be sneaky traitors. Plastic absorbs odors over time, and a scratched tray is a battlefield for bacteria. If your tray smells like a rubber band, your cubes will taste like a hardware store.
Silicone trays are better but still can cling to soap residue if you wash them improperly. Pro tip: wash ice trays with hot water and baking soda, not soap. Soap leaves a film that tastes like a failed science experiment. Your cubes should taste like mountain spring, not a dishwasher’s last cycle.
Your Freezer Needs a Breath of Fresh Air

Do a quick audit of your freezer. Throw out anything with a leaky package or a suspicious expiration date. Wipe down the interior with a mixture of vinegar and water. It’s not glamorous, but it’s cheaper than buying a whole new freezer. Your future self, sipping a clean-tasting iced coffee, will send you a thank-you note.
