Osmanthus/Green tea “Rainbow Cloud” Chiffon Cake
Ingredients (makes one 17cm chiffon tin)
3 egg yolks
20g sugar
35g vegetable oil
45ml boiled water
1 tbsp
osmanthus flowers
1.25 tsp
matcha powder
60g cake flour (+
1/3 tsp cake flour for the patterns x 4)
Red,
yellow, green, blue wilton colours (for the rainbow)
(Meringue
for patterns)
1 egg
white
1/6 cream
of tartar
(Meringue
for cake)
4 egg whites
45g sugar
1/4 tsp cream of tartar
Method:-
1. Preheat
oven to 160°C.
2. Use a
wilton food marker to draw rainbow patterns on the chiffon tin. The marker is
fully erasable during washing.
3. Infuse 1
tbsp osmanthus flowers in 50 ml boiling water and cover for 15 mins to make
osmanthus tea. Filter away the flowers to get the tea, but keep the flowers for
the main cake batter later.
4. Beat egg
yolks with sugar with whisk till pale yellow/white before stirring in oil and
osmanthus tea (filtered).
5. Add in 60
g sieved cake flour and whisk till no trace of flour found.
6. Meringue
for patterns: Beat 1 egg white with 1/6 tsp cream of tartar till stiff peak.
7. Rainbow pattern:
Scoop out 1 tsp of egg yolk batter into 4 separate bowls each. Add in a tiny
dip of red/yellow/green/blue colours to each bowl. Add 1/3 tsp of cake flour to
each bowl and mix well. Scoop over 2 tbsp of meringue. Quickly but gently fold
it in till well-combined.
8. Use a
wilton 230 tip to pipe the red rainbow line, follow by yellow, green and blue
lines. For lines with even thicknesses, it is best to drop the patterning
batter onto the tin instead of piping directly. Bake the patterns for 1.5 min.
*For good transfer of patterns, patterned batter onto tin must be thick.
9. To the
rest of the remaining egg yolk batter, add in 1.25 tsp matcha powder and the
remaining osmanthus flowers. Mix well.
10. Meringue
for cake: Beat 4 egg white with 1/4 tsp cream of tartar till stiff peaks form,
adding the sugar in 2 additions.
11. Fold the
meringue into the egg yolk batter in 3 additions using flexible spatula or
hand.
12. Pour in
the cake batter gently over the pattern, making sure that it is covered without
air pockets. Then the rest of the batter from a height.
13. Bake the
cake in preheated 160°C oven for 20 minutes, then 150°C for 30 mins (to reduce
browning for the patterns).
14. Invert
when cake is removed from oven and unmould when cake is cool.
15. For the
clouds, sieve icing sugar over a cloud template. Gently press on the icing
sugar to make fluffy imprints. *This step to be done right
before serving.
