Fill the jar no more than a third full, add a splash of water, and pulse in 1- to 2-second bursts until it looks like snow. Use the ice-crush setting if there is one, and never run it continuously on dry ice.
Why ice is the hard case
Hard, dry cubes do not flow. They bounce off the blade, pack against the walls, and leave an air pocket where the blade spins on nothing. Liquid and pulsing are what bring them back.
How to do it
- Use cubes from a normal tray, not a solid block from a bag.
- Fill the jar a third full at most.
- Add about ¼ cup of cold water per 2 cups of ice.
- Pulse in 1- to 2-second bursts, letting the ice fall back between them.
- Stop when it is snowy, and pour off any extra water.
For frozen drinks
Liquid first, then fruit, then ice on top. The blade pulls the liquid into a vortex and the ice falls into it. See can I blend frozen fruit in any blender and does blending warm the food up — a long run melts the ice you just crushed.
Which blender handles it
Listings that name ice crushing or frozen drinks mean the blade and motor were built for it. A full-size motor is comfortable; smaller machines manage in small batches with more pulsing and wear faster. Blunt, thick blades on high-power blenders smash ice by impact — see does the blade shape matter.
What it does to the jar
Ice scratches and clouds plastic jars over time — cosmetic, not a defect. Glass does not scratch but can crack from hard impact at high speed, which is why high-power blenders use Tritan. See glass or plastic blender jar.
When to stop
If the motor labors, smells hot, or the blade spins freely without catching, stop, unplug, stir with a spatula and add a splash of water. The blade assembly is the part that wears — see the blender jars and blades page.
What readers want to know
Can any blender crush ice?
Most full-size blenders can, a little at a time. Look for "ice crushing" or "frozen drinks" in the listing, and for a full-size motor; small personal blenders and older low-power models struggle and wear quickly. Some jars are not meant for dry ice at all — the manual says.
Should I add water to crush ice?
A splash helps — about ¼ cup per 2 cups of ice lets the cubes move into the blade instead of bouncing off it. For dry, snowy ice, pour off the water afterwards or use a strainer. Without any liquid, the blade can spin in an air pocket over the cubes.
Can I crush ice in a food processor?
Yes, in pulses, a cup or two at a time, with the S-blade — the wide bowl gives more even, coarser crushed ice. Check that your manual allows it; ice is hard on plastic bowls. On this site the Ninja Professional Plus has a 1,000 W peak motor.
