1) 0.75 cup white granulated sugar + more for the pan
2) 1.5 pounds whole milk ricotta, at room temperature
3) 6 eggs, at room temperature
4) 0.25 cup all-purpose flour
5) 0.25 teaspoon salt
6) Zest of 2 oranges
7) 0.5 teaspoon vanilla extract
Steps
1) Preheat oven to 350ºF /180ºC.
2) Butter a 9-inch round cake pan with removable bottom and dust with
sugar, shaking off excess.
3) In a large bowl mix ricotta and orange zest. You can beat this for a
minute or so if you want a smoother texture.
4) Add the flour, HALF the sugar, salt, and mix well.
5) Separate eggs, one by one, putting the yolks into the bowl with the
ricotta mixture and the whites in another clean bowl.
6) Beat whites for 30 seconds and gradually add the remaining HALF of
the sugar while beating at medium speed.
7) Keep on beating at high speed until it foams and triples in volume,
but medium soft peaks form when the beater is lifted.
8) With a spatula, add the beaten egg whites to the ricotta mixture in 3
parts.
Add the next part after almost incorporating the last part.
9) After the third part is added make sure the mixture is combined.
Don’t over mix it so it rises well in the oven and the texture is airy.
10) Put in the prepared pan smoothing the surface and bake for 50-55
minutes,
or until it’s golden but the center of the cheesecake still wiggles when
lightly shaken, similar to brownies.
11) Remove from oven and let cool 10 minutes on a wire rack, then run a
smooth knife all around the sides to make sure it is not stuck.
12) Let cool completely in the pan before transferring it to the serving
plate.
I like to wrap it in plastic and put it in the fridge for a few hours or
until the next day.
Notes
1) If you must substitute ricotta, you can use cottage cheese that has
been processed with some cream cheese.
2) Adding lemon juice: the combination of both zest and juice gives it a
more intense and balanced flavor.
But don't overdo it with the juice or you'll change the texture. You can
add up to 1 tablespoon of lemon juice.
If your cheese is dry this would be perfect, but if your ricotta cheese
is on the wet side, I suggest you let it drain for a while.
3) Add cinnamon or liquors for added flavors.
4) Substitute orange for lemon or lime for variety.
