King Arthur Sourdough Biscuits - cooking recipe

Preparation

In a large mixing bowl, dissolve the yeast in the warm water.
Add sugar, salt, sourdough starter and flour. Mix well.

Punch dough down, and turn out onto a lightly floured work surface.
Roll out dough to 3/4 inch thickness.
Cut with a biscuit cutter.
If desired, dip both sides in butter. (I skip this step.).
Place biscuits on a well-greased baking sheet.
