In a mixing bowl or glass jar soak add in the juice and the dry fruits. Mix well to combine. Make sure the fruits are well immersed in the juice. (I kept for 3 days in refrigerator)
Note - You can add the chopped nuts to the soaked fruit jar just few hours ahead of baking or can add them directly onto the cake batter.
Take the cake pan, grease and line parchment paper. You can dust the cake tin with plain flour if you don't have the parchment paper. Preheat the oven @180° C for 10 minutes.
In a mixing bowl add the curd and baking soda, mix well and keep aside for 5 minutes.
In a sauce pan add the sugar and heat till it starts to melt and get a nice brown colour but do not over caramelized the sugar. Turn off and add 1-2 tablespoon water and stir well and let it cool down.
In the curd mixture add the melted butter, vanilla essence, orange juice (2-3 tablespoon from soaking )and caramelized sugar. Mix well to combine.
Sieve in the flour, spice mix powder, baking powder, salt and orange zest. Gently fold to make a smooth batter.
Add the soaked dry fruits, tutti frutti and nuts to the batter.(reserve some for topping). Gently fold. Do not over mix the batter.
Pour the batter onto the prepared cake tin. Tap the cake tin and 3-4 times to release any air bubbles.
Garnish the top with the reserved dry fruits and nuts.
Bake the cake at a preheated oven @170° C for 45 to 50 minutes. A tooth pick inserted should come out clean.
Remove from oven and allow to stand for about 5 minutes. Demould the cake and allow the cake to cool down completely. Cut and serve.
