Easy Rosemary Focaccia

Combine 5 tablespoons warm water, yeast, and sugar in a large bowl. Let stand until creamy, about 10 minutes.

Add flour and 1/4 teaspoon salt to the yeast mixture; stir well to combine. Stir in 1 tablespoon additional water at a time, if necessary, until all flour is absorbed and mixture has pulled together into a dough. Turn out onto a lightly floured surface and knead until springy, 4 to 6 minutes.

Lightly oil a large bowl. Place dough in the bowl and turn to coat with oil. Cover with a damp cloth and let rise in a warm place until doubled in volume, about 30 minutes.
