If your dough doesn’t rise, it could be due to several factors: Expired or inactive yeast: Ensure your yeast is fresh and active. Incorrect water temperature: Water that’s too hot or too cold can affect yeast activation. The ideal temperature is between 37-43°C (98-110°F). Low ambient temperature: If the room is too cold, the dough may rise very slowly or not at all. Try placing the dough in a warmer spot, such as near a heater or in a turned-off oven with the light on to create a slightly warmer environment. You can also cover the dough with a damp cloth to help retain warmth.
