I grew up loving the taste of potatoes. Then I got married, and moved East to a big city. The potatoes there tasted horrid to me. They just didn't taste like potatoes. Ugh!!!
So a few years went by, and I went home. On the way, I stopped at a rest area, and when I got out of the truck, It smelled just like a good potato aught to taste! Ah tasty Idaho potatoes. So when I returned East, I pulled out the bag of potatoes, and it said, "Grown in Michigan". Ha! Since then, I have paid attention to the flavor profile of garden ecosystems. Soil is one component of a plants flavor. It seems to me like plants that are stressed by lack of consistent soil moisture can turn taste much earthier. There are some plants (particularly brassicas) that are very difficult for me to grow properly during hot weather, due to the low humidity.
