Think all at least once, but had made something out of raw grated potato - pancakes for example? Offer you almost similar to making burgers with meat, the piquancy which attaches to the gas station with pickled cucumbers! Very tasty, with crispy crust and sour cream!
Minced meat (I have pork) mix with chopped onion and dressing.
Peel the potatoes.
Grate potatoes on a fine grater;
Squeeze water, add sour cream, garlic, paprika, salt-mix.
I used a Burger mold, but you can sculpt and hands soaked in water or oil;
The form to fill potatoes with a fork, so they do not get forms in water, halfway, to make the notch;
In the recess put the minced meat.
Close the potatoes, press the form, pressing excess moisture.
Fry in preheated non-stick pan.
Fry on both sides, after getting a good crust, reduce the heat to a minimum and cook under the lid.
