3. Use a Steam Oven or Microwave

Another effective technique is to boil water in the oven or microwave and then let it cool for about 45 minutes without removing the hot water. This will create a warm and humid environment, ideal for leavening. Make sure to keep the door closed as much as possible to maintain the conditions; be quick when placing the dough inside.

4. Other Suitable Locations

You can also consider the highest shelves in your kitchen, the top of a running appliance like the refrigerator, a spot near a heat source like the stove, or even on top of a heating pad. The perfect spot can vary from kitchen to kitchen, but it should always be warm and humid enough for optimal leavening.
