I don't know how much the food culture forms the lives of people in the country. But I bet it's huge. Encouraged by Graham Robb's
Discovery of France I've been sort of on a lost village tour (
Celestine, Village in the Vaucluse,
Anthony Peregrine's accounts of Alain-Fournier country in the Berry) of France, where villages were literally unmapped until the 20th century. Semi-troglodyte life around the fireplace during winter in Celestine's village, where as usual there was little to eat but chestnut flour, little to keep warm with but the cows ruminating in the stable across the room, and plenty of stories about wolves and imprisoned princesses to tell.
This all ended, according to the Vaucluse guy, when TV came to the town in 1963, and the outdoor boules games, evening paseo, social group meetings all disappeared over night and everyone stayed home.
