Any suggestion how I can have my daughter finish rest of her milk? (babycenter.com)
Oh, I found cocoa powder easiest to mix in by shaking — I'll put it into a small jar with some of the «milk», cap it, shake it up, pour it out, and then pour in the rest of the milk into the jar (to clean out any cocoa left behind), cap, shake, pour out, done! (fooddoodles.com)
Pour the milk / yolk mixture back into the saucepan with the rest of the milk, and return the saucepan to the heat. (theredheadbaker.com)
