This reminds me of this video that shows how Italian food is a recent invention https://youtu.be/iZZfwyKa0Lc
A lot of “traditional” national foods are like that, especially if you consider pre-columbian food traditions. If you just limit it to chocolate, tomatoes, sweet and hot peppers, potatoes, and beans, none of which were used or available in Europe until after importation, you see that it gets murky pretty quickly. Funny how we associate potatoes with Ireland, tomatoes with Italy, and chocolate with Switzerland when they’re actually all indigenous American foods.
What are some actual European foods that people ate hundreds of years before that?
From what I can find, there was a lot of barley, wheat, rye. Meat and fish. Peas, cabbage, apples, pears, grapes, honey, legumes, herbs, cheese.
Recipes turn out to be a lot of bread with cheese, meat or stews, with wine or beer. And also things like pancakes and other baked goods.
