So after returning from a holiday dinner with family, the Aged Grandmother has given you a huge bowl of leftover mashed potatoes. What to do?
Well, leftover mashed potatoes can be converted into a meal by themselves. The nice thing about Mashed Potato Pancakes is that they can be eaten at any meal: breakfast, lunch, or dinner; and even make a decent Midnight snack.
For every two cups of leftover potatoes mix one whole egg into it well. Then mix in 1/4 tsp. of baking powder, 1/4 tsp. of celery salt, and if you like onions, 1 tsp. or so of dried onion flakes. Then you basically cook them on a hot, greased grill or skillet like pancakes; turning when brown on each side. Instead of syrup, though, serve them with tomato catsup or steak sauce. A-1 or Heinz 57 are especially good.
This doesn't make a thin batter like regular pancakes, so you might have to spoon it onto the grill and flatten them out. Make sure that whatever oil you use is hot---the pancakes should heat through very quickly.
Where or with whom this recipe originated is unknown. It definitely came out of the Midwest over a century ago. Some think that it is a variation of German potato pancakes that was Americanized by immigrant housewives. At any rate, it's a good way to use up leftover potatoes.
The baking powder is the secret ingredient. If you make fresh mashed potatoes, add the same quantity (1/4 tsp. to two cups) and the potatoes won't become discolored.
