Remove
everything from the refrigerator to come up to room temperature.
Preheat
the oven to 180°C (350°F) and generously butter 2, 20cm
(or 2, 8 inch) spring form pans. If you like you can also use 2,
24 cm (or 2, 9 inch) spring form pans.
Beginning
with the sponge layer, sift the flour, baking powder and salt into
a medium size bowl.
In
anther bowl beat the 3 egg yolks with a hand held mixer on medium
speed for 3 minutes. Gradually add all but the 2 msk (2tbls) sugar
and beat until the eggs become a pale yellow color and the mixture
forms a ribbon, about 5 minutes.
Resift
the flour mixture into the egg mixture and very gently blend them
together. Then add the melted butter. It may look like there is
too much flour to go into the eggs but if you measured correctly
it will go in, just be gentle and patient.
In
a very clean bowl beat the egg whites with a pinch of salt and the
remaining 2 msk (2 tbls.) of sugar to the stiff peak stage but they
should not be dry.
Fold
in 1/3 of the beaten egg whites into the beaten egg and flour mixture
gently. When incorporated add the rest of the egg whites and fold
them in gently.
Pour
this mixture into the well buttered spring form pan and being sure
to evenly cover the bottom of the pan.
Bake
in the middle of the oven at 180°C, (350°F) for 10 minutes.
This may take a minute or two more or less. So keep an eye on it,
it should only become a light golden brown. It will puff up but
when you remove it from the oven to cool it will go back to looking
like a sponge that you are more familiar with. When baked remove
from the oven and cool on a rack. Do not remove the sponge from
the pan.
For
the cream cheese filling
Place
in a bowl large enough to hold all the ingredients put 1/4 of the
cream cheese, all the cornstarch and 1/4 of the sugar and beat this
for about 3 minutes.
Then
add the rest of the cream cheese, sugar, finely grated lemon rind
and the vanilla essence and beat until creamy.
Beat
each egg in one at a time. Then beat in the the heavy cream. Don't
over do it at this point just enough to mix it all together.
Pour
the mixture into your spring form pan containing your sponge layer,
being sure to scrape the bowl clean of all its mixture. Smooth the
top and tap the pan gently on the counter top to be sure that you
have no air bubbles in the mix.
Wrap
the bottom and sides of the pan in heavy aluminum foil to be sure
that no water can get into the pan while it is baking.
Then
place the wrapped pan into a roasting tin large enough to hold it
and pour in about 3 cm or (1 inch) of hot water. This will stop
the cheese cake from cracking while baking.
Place
the pan in your preheated oven, 180°C, (350°F), and bake
for an hour. It can take a bit longer. The center of the cake should
just jiggle a bit when you shake the pan.
When
baked remove from the oven and the roasting pan and cool on a rack
for an hour. Then remove the aluminum foil and wrap the cake, tin
and all in plastic wrap and refrigerate for at least 4 hours, overnight
is better.
To
serve simply remove the sides from the spring form pan and place
the cake with the spring form pan bottom onto a serving plate. |
