In a large pot, bring the 4 cups of water to a boil.
Add the salt to the boiling water.
In a separate bowl, add the buckwheat flour (or cornmeal).
Slowly pour in about 1/2 cup of the boiling water into the flour while stirring constantly to prevent lumps from forming.
Pour the wetted flour mixture into the pot of boiling water.
Reduce the heat to low and let it cook without stirring for about 10-15 minutes, allowing the water to be absorbed.
Once the mixture has thickened and the water is absorbed, use a wooden spoon to break up the mixture into small, crumbly pieces.
Continue to cook on low heat for another 10-15 minutes, stirring occasionally to prevent sticking.
In a small pan, melt the lard or butter.
Drizzle the melted lard or butter over the cooked žganci and mix well.
Enjoy your meal!
