One of my very least favorite things about making mayonnaise with a blender is the whole "very slowly pour in the oil in a super thin stream" part. It's far too meticulous for my liking. "It's so easy", they say..."it's fool proof!" Yeah. I call bullshit. Unless you have the patience to thinly pour out a cup of oil into a running blender for like thirty minutes, it's neither easy nor fool proof. I might just be incredibly challenged, but it's always a toss up whether or not I'm going to get that thick, glorious mayo consistency.
