Sicilian Ricotta Cheesecake

Step 1
Preheat oven to 300 degrees F (150 degrees C). Set rack in the middle of the oven. Butter and flour a 9 1/2 inch springform pan, and tap out excess flour.

Step 2
Place the ricotta in a large mixing bowl, and stir it as smooth as possible with a rubber spatula. Stir the sugar and flour together thoroughly into the ricotta. Stir in the eggs 1 at a time. Blend in the vanilla, cinnamon, orange zest, and salt. Pour batter into the prepared pan.

Step 3
Bake in the center of the oven for about 1 1/4 to 1 1/2 hours, until a light golden color. Make sure the center is fairly firm, and the point of a sharp knife inserted in the center comes out clean. Cool on a wire rack. It will sink slightly as it cools. Cover, and chill till serving time.
