The pulse option exists on most modern blenders, and it’s a very useful feature. In essence, it runs the blender at top speed for as long as you hold the button. Once you release, the blender goes back to its original speed settings. This option lets you blend in waves (pulses), using high speeds for short periods. A pulse option is an amazing tool that lets you blend evenly. It’s especially useful if some of your ingredients are stuck at the top while the bottom portion gets over-blended – a little pulse or two will help bring the stuck ingredients down towards the blades.
