6 eggs (grade C)
165g castor sugar
1 tbsp ovallete
45g condensed milk
1 tsp vanilla essence
250g plain flour
1 tsp baking powder (to be sifted 2x)
150g melted butter
1tbsp dark chocolate (I used chocolate emulco)
Grease an 8' tray and base with baking sheet. Grease all the sides of tray and sprinkle with flour. discard the balanced flour away and put aside. Melt butter and put aside. Sieved the flour and baking powder and put aside. Pre heat oven at 150 degrees Celsius.
Add in ingredients (A) into mixing bowl and beat for 1 minute or till well mixed.(don't till creamy). Add in (B) and turn to high speed for 10 minutes. Lower the speed and add in the melted butter slowly 5x pouring (make sure it has been cooled).
At this time, fold in the mixture with a wooden spoon and mix well.
Divide the mixture to 2 bowl. Add 1 tbsp dark chocolate to 1 bowl and mix well.(Don't over mix).
The other bowl leave it to original colour. Start from the centre of tray with 2 tbsp of original colour and 2 tbsp of the chocolate mixture on top of the original colour.Layered the mixture till finish. if the mixture 'senget' just leave it as it is.It will be levelled later. (For me, after finish layering, I used a chopstick and make a marking like the swissroll pattern- slowly slide the chopstick downwards, lift up and move the chopstick to the next 2cm and move the chopstick upwards, lift up and move the chopstick to the next 2cm and move downwards do this..till end of tray-to get the 'zebra' pattern)in the recipe they didn't put how to get the 'zebra' pattern..(this is tru my analysing the picture in the recipe given.When done, bake in oven using the 180 degrees Celsius for 45-55 minutes. Leave to cool before cutting.
