What direction must one stir molten chocolate

I vividly remember molten chocolate was supposed to be stirred in one direction, there was even a name for this procedure.

Sadly I forgot the name, because I always figured just googling it would shower me with results, however I can't find anything (but forum-posts that that confirm my recollection but don't give an answer other than 'who cares, it ends up in your stomach anyway').

So, what direction (clock-wise or counter-clock-wise), and how is this called again?
