I’m fascinated by the existence of so many foods. Who decided to boil tree sap for 3 weeks to make maple syrup? Who agitated cows milk vigorously for 20 minutes to discover butter? Who saw cheese for the first time and decided to still eat moldy milk?

I thank those nameless humans for their service to society.

Yogurt is also very interesting, as its bacteria originates from ants. Who would think “hmm ants have infested my milk container but hey let me taste what they did to milk anyways”
You can just leave milk out at room temperature for a few days and you’ll get yogurt. There’s tons of lactobacilli floating around in the air and on every surface. You might need ants for a specific strain, but you don’t need them if you just want any yogurt.
