1
Butter a spring form pan and line it with a circle of parchment or waxed paper cut to fit just the bottom.
-
2
Its a bit easier to cut it a bit larger and then set it in place and use a knife to trim off any excess.
-
3
Prepare the crust by mixing together the sugar, butter, egg yolk and zest in a bowl until it is a bit creamy.
-
4
You can do this is a stand mixer, or by hand.
-
5
Next add the flour and work until you get a smooth dough, dusting with a bit more flour if it seems too sticky.
-

Roll it into a ball, flatten slightly and wrap in plastic wrap.
-
7
Refrigerate for 20 minutes.
-
8
Preheat your oven to 300F.
-
9
Roll out the dough (you have to pre-bake it) to 1/8 inch.
-
10
Get it close to the size of the bottom of your tin, and then trim it in place.
-
11
You just want it on the bottom... it shouldnt come up the sides.
-
12
Bake for 20 minutes until it is about 1/2 cooked.
-
13
Remove the crust from the oven and let it cool on a wire rack.
-
14
Reduce the oven temp to 275F.

16
In a separate bowl, beat the egg whites until they are stiff, then slowly add the sugar and the flour to the egg whites.
-
17
Fold half of the egg whites into the cheese mixture to lighten it some.
-
18
Then, fold the cheese mixture into the egg white mixture.
-
19
Spoon over the crust until the pan is about 3/4 full.

You need a little bit of room, because the cake will puff up during baking.
-
21
Bake on the middle shelf of the oven for about 1 hour, or until it is firm.
-
22
Allow to cool.
-
23
It will sink during this time... thats what the fruit topping is for.
-
24
Serve topped with fresh berries, orange slices, etc... anything that is not too heavy as you dont want the cake to compress even more.
