Gradually add yeast mixture, stirring with a wooden spoon to combine, then mixing with your hands until a firm dough forms. Knead dough briefly to form a ball. Transfer dough to a clean bowl, cover bowl with plastic wrap, and let dough rest in a warm spot to rise until doubled in bulk, about 1 hour.
