We make potato and leek soup to assess the blender's ability to produce a uniform puree with no lumps of potato or leek. We chop carrot and crush ice to assess the blender's ability to chop and crush evenly. The performance score accounts for 60% of the overall score.
(A) In our last test we found all the models we tested to be excellent for blending and emulsifying. So we didn't conduct these tests this time around, so some models don't have a performance score.
