@johnpowell You are not alone in your curiosity. This question intrigued me, so I googled “cheese from breastmilk” and found this blog post.
What the author of the blog post learned is that you can not make cheese from breast milk because the protein content is too low and breast milk does not curdle. This is good news for babies, because it means they can digest it (unlike straight cow’s milk) but bad news for cheese makers across the world.
However, if you manage to find a lactating woman what an interesting Craig’s List ad that would make maybe she can sell you some of her milk so you can try the recipes in that fascinating link @PandoraBoxx found. It almost makes me wish I was still nursing. I’d love to make one of those recipes and tell people when they were halfway through eating that it contained breast milk. :)
