I have previously made giant jaffa cakes and so knew the basic process - sponge, jelly, chocolate. hough this gives an authentic looking jaffa the scent and flavour are somewhat lacking so it was necessary to experiment.
As I have mentioned there are three basic elements to a jaffa cake and it was essential that each was perfect.
I began with developing the sponge. I began with my basic victoria sponge recipe (as borrowed from the WI - weigh eggs, then add equal weight of butter, sugar, flour. 2tsps baking powder 1tsp vanilla). This didn't quite give the right texture and also was too soft...jaffa hovers somewhere between cake and biscuit and I needed to replicate that. My eureka moment came with this recipe. Right texture and it added another citrus element to the jaffa helping create the right scent and flavour.
Now - the squidgy bit.Really had to play with orange products for this. I began with a basic orange jelly and initially added orange juice. Good but lacking sweetness and depth. I attempted orange squash and jelly - way too sweet and sickly..even for a jaffa! My next addition was orange essence and it seems that a heady combination of orange juice, orange essence and orange jelly brings you to jaffa! Just a heads up..the oils in the orange essence do lead to some spotting in the chocolate.
The chocolate was simpler - Initially I toyed with the idea of chocolate flavour coating to really copy the original but flavour wise this just didn't work so I opted instead for a 74 percent dark chocolate which worked beautiful both in flavour and scent.
So..basic process mastered!
Next issue was how to present the cake. Not possible to directly stack them...pillars would look a bit naff so I opted for a staggered stand and acrylic cake boards with clusters of real yellow roses on each cake.
And here...if you're still with me...is the end result....
