A PRACTICAL GUIDE
Clear ice care.
How to use it well.
Clear ice is not difficult to handle, but a few simple habits make the difference between a cube that looks great in the glass and a cube that cracks on contact. This is the practical side of the craft, written from a Malaysian supplier's perspective. Use what is useful.
1. Temper before use.
Take the cube out of the freezer and let it rest at room temperature for 2 to 3 minutes before any liquid hits it. The surface frost evaporates, the outer millimetre warms slightly, and the cube becomes ready to receive a chilled spirit or coffee without thermal-shock cracking.
Cubes go straight from a -18 Celsius freezer into a 22 Celsius glass with a sub-zero pour. That is a swing of 40-plus degrees in seconds. Tempering reduces the gradient. Skipping it is the single most common cause of split cubes.
2. Pour slowly, down the side.
Once the ice is in the glass and tempered, tilt the glass slightly and pour the spirit down the inside wall, not directly onto the ice. The liquid wraps around the cube instead of hammering it.
For engraved cubes specifically: pour on the side opposite the engraved face. The engraved surface has more total area exposed to liquid and so melts a little faster. Keeping the spirit off that face directly preserves the logo for longer.
3. Match shape to glass.
- Sphere 5.5 cm. Rocks glass or Glencairn-style whisky glass. Wide enough to seat the sphere with a small gap. See sphere →
- Cube 5 cm. Standard rocks glass, lowball, or Old Fashioned glass. See cube →
- Cylinder 4 by 11 cm. Highball, Collins glass, tall tumbler. See cylinder →
- Column 4 by 4 by 10 cm. Narrow tall glassware where a cylinder will not fit. See column →
- Engraved cube. Same as the 5 cm cube. The engraved face goes outward, toward the viewer. See engraved →
4. Storage.
We deliver clear ice insulated and sealed. If you are not using it immediately, transfer the cubes to your freezer in their original packaging, or into a clean sealed container. Avoid open trays in the freezer; the cubes will absorb the smell of whatever is in there with them within hours.
Use within a few days for best clarity and flavour. The ice does not spoil, but absorbed freezer odours accumulate over time. If you are a bar with high turnover, this is a non-issue. For home use, plan to use within a week.
5. Handling tools.
Use ice tongs, not bare hands. Bare hands leave a residue and warm the cube unevenly. Stainless steel tongs work well. Avoid plastic tongs that can snap on a 5 cm cube under grip.
6. When ice arrives slightly melted.
Even with insulated delivery, on a hot KL afternoon a small surface melt is normal. The cube is still clear inside. Pat the surface dry with a clean cloth before serving and the cube performs the same as fresh-cut.
FAQ
Why does clear ice need tempering?
Tempering is resting the ice at room temperature for 2 to 3 minutes before contact with liquid. Skipping it can cause thermal-shock cracks the moment a chilled spirit hits a deeply frozen cube.
Can I store clear ice in my home freezer?
Yes for short periods, but home freezers absorb odours from food. Store the ice in a sealed bag or container. Use within a few days for best results.
How do I pour onto an engraved cube without ruining the logo?
Tilt the glass and pour along the opposite side from the engraved face. The logo surface melts a little faster, so keeping liquid off it directly preserves the engraving for longer.
What glass works best with a clear sphere?
A rocks glass or Glencairn-style whisky glass, wide enough to seat the sphere with a small gap.
