Take a mixing bowl and the feta cheese, graviera, gouda, and milk.

Using a blender, combine the mixture until you get a sticky paste-like consistency.

While blending, season with paprika and pepper.

If the texture is too runny, add some breadcrumbs and mix well.

Next, you need to allow the mixture to firm up. For this, cover the mixing bowl with plastic wrap and set it aside in the fridge for 30 minutes.

Once the mixture is thick and nice, take it out of the fridge and roll it into balls. The preferred size is that of a golf ball, but it totally depends on you.

Add some flour to a plate and roll the balls into flour. Set aside the cheese balls dipped in flour for 10-15 minutes.

Take a deep frying pan and heat the vegetable oil to 350°F. Once hot, slowly drop the cheese balls into the frying pan. Don’t put all the balls at once but in batches. This will allow the cheese balls to cook evenly.

Fry the balls for 2-3 minutes until they turn golden brown.

Remove the fried feta cheese balls from the pan using a slotted spoon and place them over a paper towel to remove any excess oil.

Serve hot with marinara sauce.
