Yeast works on its own schedule. If the room is cold, your dough might take hours to double. If it’s drafty, the yeast get chilly and stop. I once left dough in a chilly kitchen overnight and woke up to a sad, flat blob.

The perfect proofing spot is warm and humid. Turn your oven on for two minutes, then turn it off. Stick your dough inside with a cup of boiling water. That steamy cave is the yeast spa. They’ll inflate in no time.
Fun fact: Some professional bakers use proofing boxes that cost hundreds of dollars. Others just put the dough in their car on a sunny day. Yes, a car. It’s like a greenhouse for your bread. Just remember to take it out before you drive to work.
The Final Boss: Old Yeast
Check the expiration date. Yeast is alive, but it doesn’t live forever. Dry yeast dies after about a year. Fresh yeast dies in weeks. If your yeast is old, it’s like trying to wake up a hundred-year-old turtle. It might move, but very, very slowly.
You can test it! Mix a teaspoon of yeast with warm water and a pinch of sugar. Wait ten minutes. If it foams up like a science fair volcano, you’re golden. If it just sits there looking dead, it is dead. Buy new yeast. It’s cheap.
Did you know that ancient Egyptians made bread without any yeast at all? They just left flour and water out in the open air. Wild yeast floated in and fermented it. Your starter is a wild party of invisible airborne creatures. How cool is that?
