Start by adding the butter to the hot milk in a large saucepan over medium to low heat, stir everything thoroughly until the butter is completely melted and lower the heat.
In a medium bowl, add the eggs and beat everything thoroughly until well combined.
Pour these beaten eggs into the milk and stir everything thoroughly to combine.
Then, add the sour cream, turn up the heat to medium-low and stir until it starts to boil.
Season with the salt and keep stirring until the whey separates from the curds.
Next, remove all the curds from the saucepan using a skimmer.
Transfer to a cheesecloth-lined strainer, press firmly and place a pot on top to press the cheese.
Place it in the refrigerator and let it chill for at least 12 hours.
After this time has passed, spread unsalted butter on the slices of bread.
Place the slices in a large skillet over medium heat and toast them until golden brown.
Next, unmold the cheese.
Serve it with the toasted bread slices we prepared.
