These Sourdough Biscuits are tall, fluffy, naturally tangy, and perfectly crispy on the outside. They come together in 30 minutes with no overnight resting needed.
Preheat your oven to 425°F and line a large baking sheet with parchment paper.
In a large bowl, combine the flour, baking powder, sugar, and salt. Grate butter into the flour mixture.
In a medium bowl, whisk together the sourdough discard and milk until completely smooth.
Pour the milk mixture into the flour mixture and mix until just barely combined. It's okay if it's crumbly still- it will come together in the next step.
Turn dough onto a generously floured surface. Roll the dough out to about ½ inch thick. Fold the left third over the center, then fold the right third over that (like folding a letter). Turn the dough and repeat the rolling and folding 2 more times. Roll about 1 inch thick.
Cut the dough into circles and transfer to the baking sheet with some space between each one.
Bake for 13-15 minutes, or until golden brown. Brush with melted butter.
