Yes, you can blend ice in the Tall Cup if you add enough liquid to your mixture. We recommend that ice comprise no more than 25% of your overall ingredient volume. When using a Cup attachment, after two consecutive blending cycles, wait 10 to 15 minutes before blending another cycle. Never attempt to open the Cup if it is warm to the touch. If the Cup and its contents feel warm to the touch, allow to cool for at least 30 minutes before attempting to open.
