Made my first foray into sourdough biscuits this morning using my own sourdough starter. I am super happy with the results. I used the below recipe, cast iron version. The only deviation was that my dough balls were closer to the size of a peach than to a walnut, because I like my biscuits big.
The dipping in butter thing gave them a really nice surface. I'm really happy with the flavor of my starter as well. I used the "wild yeast" method.
Ate one with blueberry jam, and one with orange blossom honey from the beekeeper neighbor. Super tasty. I think Gus McCrae would give me a thumbs up (other than using an oven instead of a campfire).
