For a short outing, walk, or warm commute, a cold drink can make the day feel easier. Round ice prepared at home helps keep the drink colder without adding extra steps in the morning.
What to keep in mind
Fill the mold the night before and place it on a level surface in the freezer. Avoid overfilling, and keep it away from strongly scented foods while the ice sets.
Before and after use
Before adding round ice to a bottle, check the opening size. If the ice feels tight, do not force it through the mouth of the bottle; use a cup or a wider bottle instead.
A quiet fit for everyday cooking
To release the ice, let the mold sit briefly at room temperature and press the silicone gently. After use, wash and dry the mold completely so it is ready for the next outing.
