Melt the butter in a suitable container. Add 2 tsp paprika to it and boil for 1 sec.
Bring 9 1/5 cups (2.2 L) water to a boil in a deep pot. Salt and pour in the cornmeal while stirring intensely and nonstop. It needs to become like a paste but still able to be poured. Remove from the stove and stir 2-3 min.
Spread out a little of the butter along the bottom of a tray and pour in 1/2 the cornmeal.
Arrange the feta cheese, sliced into thin sheets, pour in 1/2 the warm butter and cover with the remaining 1/2 of the cornmeal. Sprinkle with crumbled feta cheese.
Pour the remaining butter on top and put to bake for 5-6 min. until the feta turns crunchy.
