The greatest lesson came with the realization that good food cannot be reduced to single ingredients. It requires a web of relationships to support it.

If you just think exclusively about what would be the best tasting or the most profitable, you're just not seeing the big picture.

The history of food has never had a better biographer. Required reading for anyone who eats.
