How do you make yeast from potatoes?

You can't actually make yeast from potatoes. Yeast is a living organism, and you can't create it from scratch.

Here's the breakdown:

* Yeast is a fungus: It's a single-celled organism that's different from potatoes.

* Potatoes are starchy vegetables: They provide food for yeast, but they don't contain yeast itself.

What you can do with potatoes and yeast:

* Use potatoes to feed yeast: Potato starch provides the sugar that yeast needs to grow and ferment. This is common in making bread, beer, and other fermented products.

* Start a sourdough starter: This involves combining flour and water, which provides a suitable environment for wild yeast to grow. Potatoes are not involved in this process.

It's important to remember that yeast is a living organism and requires specific conditions to thrive. You can't just make it from scratch. You need to purchase active yeast or find wild yeast in the environment.
