Do I make changes? Of course. Remember that all cuisines originated in subsistence cultures, when the preparation of food was not an option and the amount of time it took was less of an issue. We are freed not only from the burden of raising chickens, for example, but of raising the food needed to feed them and even of cutting them up. We neither pick olives nor brine them. We neither grow corn nor dry and grind it for meal. Nor do we need to think about any of these things months or years in advance or worry—much—about whether it rains.
