So, what's the role of yeast in all this? Well, yeast is like a tiny little factory that produces carbon dioxide gas, which gets trapped in the dough, making it rise. But, if your yeast is old or inactive, it's like trying to start a car with a dead battery - it's just not going to happen!
And then there's the temperature factor - yeast loves warmth, but not heat. If your oven is too hot, it's like trying to grow a plant in the desert - it's just not going to thrive! So, what's the perfect temperature for yeast to do its thing?
It's around 75°F to 85°F - that's like a comfortable summer day, perfect for a yeast picnic! But, if your ingredients are too cold, it's like trying to have a party in a refrigerator - it's just not going to be fun!
