There are a few ways to crush ice at home, depending on what tools you have available. If you have a blender or food processor, simply add the ice and pulse until it reaches the desired consistency. For a more manual approach, place the ice in a resealable bag and use a rolling pin or other heavy object to crush it. Or, fill a bowl with ice cubes and use your hand or an immersion blender to break them up. Once you've crushed the ice, it can be used for any number of purposes, including adding to drinks, making snow cones, or using as a cold compress.
