(A) In the past we've found all stick blenders to be excellent for blending and emulsifying so we now only conduct chopping and processing tests. Only the models that come with a separate chopper/processor unit are subjected to the chopping and processing tests.
Chopping: We assess the blender's ability to chop carrots evenly.
(B) These models claim that their blade can chop. When we tested how well the blade works we found it to chop carrots very well.
Processing: Making a pesto sauce, we assess the stick blender's ability to process the ingredients evenly.
