Ima post this here too. This manga is setting up some European situation that never existed in real life. No spices equal bland food? Really? Have you actually been to Europe Author?
Where's the cheese, dairy based foods, the sausages, pickled foods that real Europeans eat? Yes no potatoes or tomatoes, but really, no mention of European specialties like Ham, Jerky, Pies etc? REALLY? They spent months preparing for winter, Europe had plenty of time to make tasty preserved foods like the rest of the world. Also, if the food is bland, WHY DON'T YOU COOK IT IN ANIMAL FAT LIKE EVERYONE ELSE DOES.
Also, does the author not understand butter is life and Olive oil and Eggs are great in Europe? Or that Raisin bread in Europe where wine and grape cultivation was common? How about Fruit pies and traditional fruit based drinks and foods? Or beans yeah? You would be surprised how good beans taste when cooked correctly. Actually, how about anywhere that bread is made was probably good at finding ways to make it tasty.
And if the bread is so hard. . . . . DUNK THE DAMN BREAD IN THE SOUP. Everyone does it JUST DO IT. MAKE YOUR DREAMS COME TRUE. NOTHING IS IMPOSSIBLE, JUST DO IT!
