Why does your ice cubes taste like ether?

If your ice cubes taste like ether, it could be due to contamination from the freezer or the water source used to make the ice. Ether-like flavors can arise from chemicals or substances stored in the freezer, or from impurities in the water itself. It's also possible that the ice cubes absorbed odors from other foods. To resolve this, try cleaning your freezer and using filtered water for ice production.
