Choose your own ending Chocolate Pudding

Ideally, start with an 8 cup Pyrex™ measure, or else be prepared to watch closely.  Add 3 1/2 c. Milk, 20 Scharffen Berger petite baking chocolate squares (I think this comes to 5 oz.), 1/2 c. Sugar and 1/2 t.salt.  Start the microwave for 10 minutes.  Now take 3/8 c. Cornstarch and whisk with 1/2 c. Milk.  Next start whisking the mix in the microwave.  It may take a few visits over a minute or two.  Add the cornstarch mix and whisk the whole thing we every minute or so. After 7 minutes or so, the mix will foam at the top as it starts to boil.  Whisk it down every 30 sec. Or so.  After the ten minutes are up, it should have some body and show a whisk Mark.  Remove it from the microwave and whisk it every few minutes until you can touch it (maybe 105 degrees).  Then add 3  tablespoons of the liquor of your choice – Drambuie, Cointreau, sham board, etc.  Or Chambord if you like Francois I better than you like voice recognition.  And put it in the frig.
