No one writes an expiration date on a homemade loaf. So how do you know? You sniff it. If it smells like a bakery, you’re golden. If it smells like a damp sock that went to a pumpkin patch, toss it. Mold can show up fuzzy and green, like a tiny alien invasion.
I once had a loaf that looked fine but smelled like a forgotten gym bag. I tried to toast it anyway. My toaster still holds a grudge. Trust your nose; it’s never lied to you about pumpkin bread.
Also, if you see any blue or green fuzz, that’s not a new spice blend. That’s mold saying, “Your time is up.” Throw it away with dignity. You can always make more.
