Did you know all cheese is, essentially, made with 4 ingredients? And did you know that one of those ingredients has been outsourced to Pfizer?

Okay, not exactly, but essentially. When you start to research today’s topic– fpc rennet –you will find yourself down a dark rabbit hole without much transparency.

In today’s episode, Robyn Jackson, of Cheese From Scratch, opens this can of worms with us.

Join in as Robyn:
--walks us through the history of rennet
--explains why rennet is essential in cheese
--describes 3 ways that rennet is made, including one that’s the same as Ma Ingalls used in Little House in the Big Woods
--describes what happened in the 70s that drastically threatened the world of cheesemaking
--tells us what pfizer did in the 90s that changed everything
--assures us that, in addition to making our own cheese, there is one thing we can do to avoid GMO-derived cheese

So whether you want to learn to make your own, or you just buy some cheese sometimes, this episode is for you!
