More of this lazy "yeah this entire planet apparently has zero culinary development, even though ingredients are everywhere and everyone is so starved for flavor they goes nuts over simple cooked rice."
With how fast boring ass foods are spreading, you'd think one person in this kingdom would knock some braincells together do try something truly bizarre like put jam in bread....but apparently this is another one of those isekai worlds where everyone is brainless.
Come on. Why not instead show us some bizarre otherworldy food? That'd be a little neatnat least. "Reintroduce earth crap to otherworld" is already excessively overtread ground.
