Here is one way of making Kotlet…believe it or not there are a few types and different ways to make Kotlet.
.5 lb ground beef– I used ground beef with only 10% fat
1 small onion
1 large potato
baking powder (optional)
1 egg (optional)
You can use a blender/food processor to chop up the onion and potato, or you can use a grater. Some people like to boil the potato then mash it up, and others use the grater or food processor. I have made Kotlet using both techniques. Here I used my blender and chopped up the onion and potato (I also hit the puree button to make sure it was mixed well). Afterward, you can pour the contents in the blender (or food processor) in a bowl with the ground beef and mash them together. Add turmeric, salt, pepper, and if you like baking powder, the egg, and bread crumbs. You can also choose to not put bread crumbs in the mix, but rather rounded balls of the mixture in the bread crumbs before flattening and frying.
Adding the baking powder and egg will keep the mixture together and allow it to puff up. I did add them, but noticed that my mixture wasn’t sticky enough, so I added my bread crumbs to the mixture. Usually when you boil the potato that is when you want to add the egg to the mixture.
After all the ingredients are mixed and mashed up you will take portions and form round balls out of them and flatten them out in your hand then place the patties (Kotlet) you have formed into a frying pan that has oil you have already heated. Fry each side until golden brown.
