Heavily salt a large pot of boiling water and add 1 lb of ziti. Cook until al dente.
In a mixing bowl add Ricotta, 1/2 cup of grated Pecorino Romano cheese, about 5 oz. of mozzarella chopped into 1 inch cubes, 2 ladle fulls of homemade sauce (about 1 cup), plenty of cracked black pepper , and about 1 tsp. of kosher salt.
Mix the ingredients in the bowl. The result should be a pink color after mixing. If it's too white...add a little more sauce.
Then, add the cooked ziti into the bowl and mix all together.
In a casserole dish I used: 15.25 x 9.87 x 6.50 Inches (LxWxH) layer in this order:
enough sauce to cover the bottom of the dish with a thin layer
half of the ziti mixture
cubed mozzarella
Pecorino Romano
cracked black pepper
fresh parsley
rest of the ziti mixture
more cubed up mozzarella
more grated Pecorino Romano
more sauce (about 2 ladle fulls) thick layer
rest of the cubed mozzarella
grated pecorino romano
cracked black pepper
and fresh chopped Italian salt leaf parsley
Cover with foil and bake 30 minutes at 400 degrees F.; then uncover and bake another 30 minutes at 400 degrees F. or until browned and bubbly! (about 1 hour total cooking time)
Cool the baked ziti a 1/2 hour before serving! It will set up and become firmer!
