It's hot in our little cramped apartment in Toronto. And I come back to my mom, who's already like setting up for dinner. And she's like, clean up after yourself. Your breakfast is on the counter. And then I go like, sorry, mom, pick up the bowl. And the milk is set. It's like jelly. I'm like, mom, what has happened? She's like, you made yogurt. Now, please clean it up.

We have we have stuff to do. And I was like, no. How can I make yogurt? That is something you buy. I can't just leave the house one day and make Lego when I come back. That's something you buy from a toy store. Yogurt is something you buy from the grocery store.

But yeah, I was doing research and I was like, oh wait, all these microbes that live in your mouth are the same microbes that people have used for fermentation for thousands of years. Like the reason you have to brush your teeth is because lactic acid bacteria eat all the food that doesn't make it down your esophagus.

And turn all those scraps into lactic acid, which then rots urine out and corrodes it.

And that is the same action.

Exactly. And if you're lucky, they're there in the right amounts to do what they do in yogurt. And acidify the milk, coagulate the milk proteins, and make this gel.

You need food. You need food that you would want to eat that hopefully also the microbes will want to eat. So to start any fermentation process, you need the food you're looking to ferment. Then you need to find the microbes. There's a couple ways of going about that. One, they're everywhere. That's good. It's good that they are everywhere. They're on you. They're on our skin.
