In my forties I had a short fling with a woman who was still breastfeeding her son, and her pumps runneth over.
Human breastmilk is really sweet for those of us used to cows milk. Or really, too sweet for anyone with more than one digit in their age. The quantity available had me pondering the possibilities of small-run cheese or ice-cream production.
I suppose breast milk can be a fine substitute as a coffee creamer or in some dishes, but drinking it directly is an...experience.
