In a heavy sauce pan over extremely low heat (or double boiler) mix "with a little cold milk":
1/2 cup sugar
2 heaping Tbls cornstarch (i swear Argo works best)
3 egg yolks
3 Tbls of cocoa
Another option to help avoid scrambled eggs is to gently heat the above ingredients minus the eggs. whip up the eggs in a bowl and ladle in small amounts of the warm liquid (while mixing) to temper the eggs.... keep adding warm liquid and stirring until they are almost as warm as the liq. in the pot, then pour them in.
BBH, you CAN make pudding with stevia!!! You need to use a lot with chocolate, and it won't be as sweet, but it is still yummy! Use bitter baking chocolate or add Hershey's baking cocoa to the first step.
I don't have a double boiler so I set a stainless steel bowl on top of a sauce pan and it works great!
golly i hadnt thought about that either.. i like dark, bitter chocolate so i was considering using less sugar anyway.. but your stevia may be the ticket. hum....
i learned how to make this so long ago that i never think about how not to kill the custard... i'm so used to doing it i cant even think about how to explain it.
one of my friends has another way to avoid ruining the eggs... by putting them in at the very end (thats how her grandma made it). but now i cant find her notes on how to do it....
