Going back a few years, I would think nothing of driving around Melbourne in search of an ingredient that was out of season and therefore hard to find, but for a recipe I desperately wanted to cook. And I guess that was a sign of the times - trends were more about impressing with ingredients that weren't readily available.
Yet now things have turned full circle, mimicking an age where communities were smaller and more self sufficient. They didn't travel for days to find a certain species of mushroom. Greenhouses weren't used to grow strawberries out of their natural season. Food was grown in season, locally, and diets were seasonal, reflecting the produce available naturally at that time.
