Whoever said lasagne needs Jesus.
If you only tasted authentic homemade lasagne just out of the oven you’d know the lie you’ve been living. My grandmother was probably hired as God’s personal cook when she died, and I can tell you, there was no way of getting back the original taste of her food after it went cold. It was still above some of the best food you could hope for on your average Tuesday, but never, never as divine as when it was fresh.
Actually, I’ve never had homemade food that tasted better reheated. Maybe some industrial stuff could actually taste better, but that’s not exactly a feature I’d put on the package.
