Learn how to get clear, odor-free ice cubes every time using the playful Ice Cub tray from OTOTO DESIGN, plus tips for creative frozen treats.

Quick Answer

For crystal-clear, easy-to-release ice cubes, use filtered water, fill the Ice Cub tray only to the fill line, and freeze for at least 6 hours before popping them out.

Why the Ice Cub Tray Is Different

The Ice Cub tray from OTOTO DESIGN isn't just a mold—it's a playful cat-shaped silicone tray that makes freezing and releasing ice effortless. Its flexible material prevents cracking and sticking, so you get perfect cubes every time without twisting or banging.

Common Mistakes to Avoid

Overfilling is the top error. When water expands as it freezes, too much liquid can cause the tray to bulge and cubes to fuse together. Another mistake is using tap water with high mineral content, which leads to cloudy ice and off-flavors.

Step-by-Step Guide to Perfect Ice Cubes

Step 1: Choose Your Water: Use filtered or distilled water for the clearest cubes. Tap water with high mineral content will produce cloudy ice and may carry a slight taste. If clarity matters, boil tap water first, let it cool, then freeze.
Step 2: Fill the Tray Correctly: Pour water into each cavity up to the fill line (about 90% full). Overfilling causes cubes to fuse together when the water expands during freezing. Use a small pitcher with a spout for precise pouring.
Step 3: Freeze Flat and Uncovered: Place the tray on a level surface in the freezer. Do not stack anything on top. Freeze for at least 6 hours or overnight for fully solid cubes. Freezing uncovered allows any residual odors to escape, keeping ice fresh.
Step 4: Release Gently: Twist the silicone tray slightly from the bottom, then push each cube out from the back. Never use metal tools or hot water, which can damage the silicone. If cubes stick, let the tray sit at room temperature for 2 minutes.
Step 5: Store Properly: Transfer cubes to a sealed freezer bag or container. Leaving them in the tray long-term can cause odor absorption and freezer burn. Label the bag with the date; cubes stay fresh for up to 2 weeks.
