Reusage of deep frying oil and flour coated vegetables
Cool oil.  Filter through coffee filter.  Store in refrigerator.  You can reuse.  Heat oil to deep fry temp.  Fry a neutral piece of bread.  Taste.  You can reuse your oil as long as it doesn't impart an off taste to the bread.  My guess is that, in a stove top situation, you won't get more than one or two uses before the oil is degraded too much for frying.
