I handle NPD for a confectionary company, there are 3 tempering units in the R&D kitchen that have Milk, Dark and White Chocolate in them when developing new recipes. If I'm having a really shit day I gown up and get a sample jar from Quality Assurance, fill it with tempering milk chocolate and drink that back at my desk.... its proper chocolate not the thin stuff for decorating.

Its like straight up chugging happiness.
