My son in law got fed up during the early shutdown when his local bakery was shut down, and decided, heck I’ll learn to make it myself, but there was no yeast to be had in the Northeast.
He’s a smart one! I learned from him about how to bake bread without Fleischmans!
We have really learned a lot. He makes the best everything, and it is incredible, fun, and yummy. I don’t make it, he does it.

You’re correct. Make your own starter. I’ve done that a couple times.
