Quite a few years ago we conducted an experiment, trial of a sort. There are two types of spinach, Flat Leaf and Savoy. We planted both types in the field at the same time. One week the flat leaf was harvested for the box and the next the other. We asked for your comments. Overwhelmingly, the Savoy was preferred. Yes it is much harder to wash away the dirt, but the flavor is far superior.  This year’s rains have almost covered the spinach leaves in a thin layer of soil at times. We do rinse the spinach, but do not thoroughly wash it. Washing can damage the leaves which is why spinach in the store is typically flat leaf, as it is so much easier to clean. Your comments and questions are always appreciated. -Nigel
