It is difficult for us to find specific books related to it in medieval aristocratic dinners, but surprisingly, at the banquet hosted by Gaston IV, Count of Fuwa, in Tours in 1457, we could get a glimpse of the tip of the iceberg of aristocratic dinners: at the beginning of the banquet, bread pieces were served, and everyone ate them with nourishing wine dipped in ginger juice, followed by "Big Mac pickled chicken legs", "wild boar ham" and rose perfume. However, aside from material richness, we can sniff out dangerous political information from it. The frequent appearance of Hungarian badges is meaningful at seemingly striking dinners. In complicated banquet etiquette procedures, nobles are always reminded to correct their political attitudes.
