For best results, make sure your sourdough starter is very active before mixing the dough, and adjust fermentation time based on your kitchen temperature, giving more time if the dough looks sluggish and less if it rises quickly. A well-fermented dough will look aerated and jiggly when you shake the pan gently, which leads to an open, soft crumb. Keep your fingers well oiled when dimpling so you don’t tear the dough, and avoid pressing the gas out completely—those bubbles are what make focaccia light. You can vary the herbs to your taste, add toppings like cherry tomatoes or olives after dimpling, and if the top browns too fast during baking, loosely tent with foil for the last few minutes.
