Ben, what a very nice meal. As per the spinach your description made me wonder if it was so-called baby spinach in a bag, because I have in the past gotten a weird unpleasant chemical flavor from such a product. Otherwise maybe it was spinach + cast iron + acidic cider. Not from a bag, but fresh. The reaction in the cast iron perhaps, I suppose I could run some tests to see. It was really wierd, I would liken it to a very strong taste of beets with a slightly chemical edge. Thanks! Ben
