Cold weekend with not much to do, so I put some of my material together and created a doc of 3 lessons that should be able to turn any beginner into a dutch oven cook.
This is based on almost 35 years of dutch oven cooking and over 50 with cast iron.
Some of it don't agree with some of the YouTubers, may not agree with what your mom or grandma told you, but I have done countless experiments to find out what was right and back my statements with science.
The link goes to a free forum board, I set it up as a public access cloud. My IT SIL suggested it as a simple way to allow me to share my materials with links.
There is much good material there on that site, most of it mine, fee free to look it over and see if it's helpful to you.
