What are mashed potato patties?

Mashed potato patties are "burgers" made by combining mashed potatoes and other ingredients including a binder of some sort and egg, then frying them until golden.

Where do mashed potato patties come from?

Potato patties, also called latkes, were invented in Eastern Europe in the mid 1800s when crop failures in Poland and the Ukraine led to the mass planting of potatoes.

How do you keep potato patties from falling apart?

Be sure your patties aren't too wet and that you've used an adequate amount of binder.
