You don't have to drizzle the oil at all. You just put everything,
(egg, oil, lime juice, dry mustard, salt ) in at once and then put
stick blender to the bottom of the jar before you turn it on. Then
turn it on, and rock it slowly side to side while bringing it up to the
top. Takes a few seconds only. See my posting above.
