Have you used Carl Griffith's 1847 Oregon Trail sourdough starter?
I'm not a sophisticated baker yet. I use a bread machine, and I've made sourdough from about 10 different recipes with wildly different results, some fairly good (and some inedible). Always, though, I wish it had more of that "sourdough" flavor, more like the white-flour sourdough loaves/boules I've eaten in California. I've taken to adding a tiny bit of sour salt (citric acid) to my bread, but it's not the same.
I'm not yet ready for jo_en's CLAS, FLAS, and TH-SD - I don't have the ingredients, a crockpot, or the courage yet!
I wonder if the starter would give me different results. I currently use the one from Breadtopia. I have no complaints, but I wonder how it would compare with Carl's... Would it taste very different?
