Watermelon Jalur Gemilang Cake

Makes 8 pieces

 

INGREDIENTS:

WATERMELON SPONGE

100 g egg yolks

20 g cooking oil

100 g watermelon reduction (slowly reduced from 5 ripened red watermelons)

30 g baked stable red yeast powder

10 g milk powder

0.5 g salt

2 whole eggs

80 g plain flour

170 g egg whites

1 g cream of tartar

80 g fine granulated sugar

 

METHOD:

1. Preheat oven to 180 degrees Celsius and line a 14 x 14 inch tray with parchment paper.

2. Place egg yolks, cooking oil, watermelon reduction, red yeast powder, milk powder, salt, whole eggs, and plain flour in a medium bowl. Mix well.

3. In a separate bowl, beat egg whites with one-third of the fine granulated sugar until they are frothy. Gradually add the remaining sugar in one-third portions. Continue beating mixture until it forms medium peaks and becomes a meringue. Remove one-third of the meringue and fold it into the egg yolk mixture.

4. Using a spatula, slowly stir the two mixtures together until well combined. Bake in oven for 20 minutes or until a skewer inserted into the centre comes out clean.

5. Remove from oven and allow to cool. Cut the sponge in three equal parts measuring 6 x 6 inches each and set aside until ready to use.

1 kg water

50 g sugar

2 tsp agar powder

 

METHOD:

1. Boil butterfly pea flowers in water until liquid turns deep blue. Add sugar to dissolve.

TO ASSEMBLE

3 pieces of watermelon sponge

300 g watermelon coulis

200 g whipping cream (whipped and stored in chiller to be ready for use)

200 g butterfly pea agar (liquefied)

edible gold powder

 

APPARATUS

6 x 6 inch mold

adjustable cake divider

acetate sheet

 

METHOD:

1. Spread watermelon coulis on all three sponges. Keep in chiller for 30 minutes to set.

2. Once coulis has set, spread whipped cream on only two  of the sponges.

3. Stack the sponges with the coulis and whipped cream on top of one another and gently place them in a 6 x 6 inch flexible mold or tin mold with a removable base. Place the third piece of non-cream sponge on top.

4. Adjust a cake divider to four 6 x 2 inch rectangles and lightly press (not all the way down) onto the sponge. Mark  the divided columns from 1 to 4.

5. Gently spread whipped cream on columns 1 and 3. Spread butterfly pea agar on columns 2 and 4. Keep cake mold in chiller for another 30 minutes to set.

6. Mark 4 columns on a 6 x 6 inch acetate sheet and further divide columns 2 and 4 into 8 equal squares. In the centre of these squares, draw a crescent moon and star with reference to the Malaysian flag. Gently cut out the shapes (not the squares) with a sharp art knife.

7. Place the acetate sheet on top of the cake with columns 2 and 4 directly above the butterfly pea agar. Gently dust  gold powder through the cut-out shapes to create the crescent moons and stars of the Malaysian flag.

8. Fill a small piping bag with watermelon coulis and pipe out horizontal red lines on columns 1 and 3 to create the red and white stripes of the Malaysian flag. Store in chiller for 30 minutes to set. Slice the cake into 8 pieces and serve.
