The house, for those who live there, is "the world"; the walls separating it from an "outside" that can then symbolically represent "another world", a different dimension. The roof divides the daily and domestic sphere from the sky, from the universe of the transcendent, the mysterious and the supernatural.
The threshold is at the same time the border and transit point between the two worlds (the step that almost always there is place is called in the local dialect "é mudéri", from the verb “mudé”, "change", "mutate": surpassing it incoming or outgoing will " change dimension", it operates the passage into another world).
A place is full of meanings and therefore of symbolic value when the man it conceptually trace the center and the thresholds when it defines an inside and an outside, when it marks its boundaries.
If this place is home, this process is even more immediate and important. All the existential experience of men is summarized semantically in the rural home and at crucial points of example, and gestures that there are accomplished. If the inside is the material and the known world, the family, the outside is the unknown, the transcendental.
The food has lost its symbolic communication value, mute and underground alphabet, entrusted to the senses of taste and smell that lead deep, fragrant soul of things.
Eating has never been only feed themselves, cooking has never been only prepare the food.
The passage from an external to an internal, from a natural to a cultural, requires a ritual.
