当圈圈遇见方方

这款oreo芝司蛋糕, 是第6个做给我家那台不用插电全自动洗碗机的生日蛋糕。不过说来惭愧，我做给他的蛋糕一年比一年丑。虽然我不是赖小姐，但我总认为那是因为他对我没有任何要求，即使马马虎虎做一个蛋糕来充数，他半句怨言也没有，还夸张地对着未经修饰'全裸'的蛋糕说 "Oh，it's a heart shaped cake!"

待人处事比较圆滑的他，和个性较冲动有话直说的我，好比一个圈圈遇到一个正方形。多年的相处下正方形的四个角被磨得也变得有点圆了。有烘蛋糕的您，要为圆形烤盘铺油纸时是怎么剪圆形油纸的呢？好多年前我从电视学会了Jamie Oliver的方法，就是先剪个正方形，然后对折四次，大略剪一条圆弧，打开就是一个圆形了。


所以当圈圈遇见方方，会变成什么呢？是长了角的圈圈？还是缺了角的方方？

之前都只会做免烤生乳酪蛋糕，第一次烘New York style芝司蛋糕，零经验，don't know what to expect。阴差阳错，也就将错就错，用买了N个月的心型模具。成品真的不怎样，我想还是用圆形烤盘会比较好看。因为是New York style cheesecake，所以不虽要用水浴法来烤，直接放入烤箱就可以了。照着食谱用170度烤40－45分钟，蛋糕出炉， 表面有点‘moh peng’，可能我的烤箱温度有点偏高，放凉后收缩坍塌得蛮厉害，不过我想典型的烤乳酪蛋糕也就是这个模样，所以也不当一回事，没放在心上。蛋糕完全冷却后还不能吃，更不能立刻脱模，必须连模具放进冰箱冷藏至少四小时以上，最好隔夜冷藏，味道会更好。

虽然蛋糕有点丑，不过加上一些点缀还混得过去。乳酪蛋糕部分绵密扎实，酸甜适中，非常好吃，真的有点超出意料自外！没想到第一次烤芝司蛋糕味道会那么好， 吃一片肯定不够，多吃一片也不会感觉腻腻的。家里的一大两小oreo迷，都一一竖起大拇指连连赞好。

两周后我用160度烤第二个乳酪蛋糕，表面美美毫无瑕疵，让蛋糕在烤箱里放凉，蛋糕没收缩也没坍塌。因为我对oreo没多大兴趣，我会比较喜欢这个原味乳酪蛋糕。

回到当圈圈遇见方方的问题－－－答案其实是－－－心形！
把一个圆形对剪一半，排在一个同等大小的正方形其中的两边，就成了一个心形。。。
好比我的圈圈包容着我这个方方 :)

Pardon my recent absence from this blog. I have been putting in my best effort to fulfill my responsibility as a good parent to help my younger child prepare for his mid-year exams. Sad to say this is something quite inevitable in our meritocratic education system, there is no way to avoid it but to get on with it. Since I don't send him for any any tuition or academic enrichment classes, I have to assume the role of a home tutor. Anyone who has the experience coaching your own kid would know, it is definitely not a pleasant affair. I am so glad that we can now resume our happy mother and child relationship instead of getting into that all too familiar tiger-mother-helpless-lamb situation every now and then during the past few weeks.

The highlight of this post is yet another one of my 'first attempt' for the month, or rather last month. I baked a New York style oreo cheesecake for my husband's birthday. This is the first time I have made a proper baked cheesecake. Preparing the batter was quite straight forward and that left me the false impression that the cake would turn out great. Little did I know that my oven temperature was on the high side, and upon cooling, the cake shrank and collapsed with a slight sunken top. Well, it was not a pleasing sight to behold so I decorated it with whatever I had on hand to make it look more presentable. Fortunately, the taste of the cake was not compromised at all. It had a very nice creamy and smooth texture, yet taste light with a refreshing hint of lemon. You wouldn't be able to stop at just one slice. Once we finished the cake, I started craving for another one. It is no surprise that I made another version a fortnight later, and this time I was careful to bake it at a lower temperature. I left the cake to cool in the oven when it was cooked, the cake didn't shrink or sink as much as my first attempt. Unlike my husband and my boys, I am not really a fan of oreos. So I prefer this plain version as the delicate taste of the creamy cheesecake was not overpowered by the presence of the sweet oreo crumbs. The digestive biscuit base is also a better option to pair with the slightly lemony cheese filling.

My latest baking venture has certainly removed my fear of making a baked cheesecake...I am sure I will be able to move on to making more delicate bakes such as the Japanese style souffle cheesecake...



Baked Oreo Cheesecake
(makes one 7" round cake or 7" heart shape cake)

Ingredients:

base crust:
100g oreo cookies (without the cream), finely crushed
45g unsalted butter, melted

filling:
250g cream cheese, soften at room temperature
100g caster sugar
50g unsalted butter, soften at room temperature
100g sour cream
1 teaspoon vanilla bean paste
1 large egg, room temperature
1 large egg yolk, room temperature
10g corn starch
1 tablespoon lemon juice

3 ~ 4 oreo cookies, break into small chunks

Method:

Crust:
Lightly grease a 7" round baking pan (with removable base). Line base and side of the pan with parchment paper. Combine crushed oreo cookies and melted butter together in a mixing bowl, mix well. With the back of a spoon, press the oreo cookies crumbs firmly onto the base of the prepared pan. (To ensure the crust is even, I used the base of a flat-bottom glass to press down the crumbs.)

Filling:
With an electric mixer, beat cream cheese in a mixing bowl until smooth. Add in sugar and beat till fully incorporated. Stop to scrape down the sides if necessary. Continue to add in butter, whisk to combine. Add in sour cream, beat to combine. Add in vanilla bean paste (or use the seeds of 1/3 of a vanilla pod), beat to combine.

Lightly beat the egg and egg yolks in a small bowl. Add in the egg mixture to the cream cheese batter in 3 separate additions, beat to combine after each addition. Add in corn flour and lemon juice, beat to combine.

For a smoother texture, strain the batter over a sieve. Pour the prepared pan with half of the batter, sprinkle oreo cookies chunks over the surface evenly. Pour the remaining batter. Smooth the surface with a spatula. Bake in preheated oven at 170 degC for about 45~50mins (Note: I find baking at 160 degC yields better result). To test for doneness, gently shake the pan, the filling should have a slight wobble in the centre. Once the cheesecake is done, turn off the oven. Leave the oven door slightly open and leave the cheesecake inside the oven to cool off for about an hour. The cheesecake may crack slightly if left to cool outside the oven.

Remove from oven and leave to cool completely. Do not unmould. Cover with cling wrap and leave to chill in the fridge for at least 4 hours, best chilled over night.

When ready to unmold, place pan on an inverted glass (or a canned drink or any canned food). Carefully slide the side of the removable pan downwards to release the cake. Transfer cake to a serving plate, decorate as desired.
