I"ve messed with SD for 30 years, like most cooking it is no rocket science. I really like the SD biscuits covered with butter and Orange Marmalade. That is a combo hard to beat. They need to be eaten fresh to really appreciate them. Still good later but just not the same. The quality of SD is region specific, the action is directly related to local air quality.
The starter draws spores out of the air. My Dad grew up in Virginia and always was disappointed in the SD here in WA.
The picture is a batch out of a Dutch Oven in camp, those are a real treat.
