Yes, this, exactly. I've done my own dressing for years & have recently rediscovered good apple cider & pear cider vinegars are *wonderful* for salads. There's a fruitiness to them that's really nice, esp. if you put fruit instead of tomatoes into salads. And if you like blue cheese, whisking a little bit into a basic oil & vinegar is much tastier than the glop that comes out of a jar of "bleu cheese dressing."
