Recipe: Purple Sweet Potato Cottony Cake

If there is any cake that I could eat everyday without any guilt, that would definitely be this cottony cake. Nope, chiffon don't even come close. 

5 egg yolks
2 tbsp corn oil
80 ml milk
65 gm cake flour  - sifted - set aside
50 gm purple sweet purple puree 
1/2 tsp salt

5 egg whites
3 tbsp sugar
1/4 tsp cream of tartar

1. Line base of a 8" square tin with grease proof paper.   

2. Preheat oven to 170 degrees C. Place a baking tray on the lowest rack, pour in enough water [about 1.5 cups] for steam baking, then place a baking rack over it.  

3. Whisk egg yolks until creamy then gradually drizzle in the corn oil, salt and followed by milk [continue whisking while you add ingredients]. Whisk until well combined.

4. Fold in sifted flour and pirple sweet purple purée. Mix until batter is smooth. Set aside.

5. Use a cake mixer, whisk egg whites until frothy, then add in cream of tartar.  Beat until soft peaks then gradually add in the sugar and whisk until stiff peaks formed.  

6. Fold in 1/3 of the meringue into the egg yolk mixture until combined. Then fold in the rest of the meringue lightly in two portions until well combined.  

7. Pour the batter into the prepared cake tin. Tap baking tray on work surface a few times to release trapped air bubbles before baking. 

8. Place it over the baking rack to steam bake cake in a preheated oven at 170 degrees C for 50 minutes [by then the water bath would have dried up].  

9. Remove cake and invert it to cool for about 5 minutes [otherwise the cake base may be moist because of vapour from steam-baking].   

10. Remove baking tin and the paper linings immediately and leave cake to cool on a wire rack [base facing upwards].  The cake may shrink a little when cooled [low gluten cake].

I can't express how beautiful (yummy of course) purple sweet potato purée is. :')

A few selfies ages ago. 

I obviously don't look like this anymore. My dark eye circle is beyond horrendous. T.T

You would probably never see 'naked' face like this anymore. -.-
