This cake is best eaten the next day and can be stored wrapped well for 10 days or longer.
If you wish , you can feed (brush) the cake with rum or orange juice .
Make sure your fruit are chopped small or they will sink to the bottom (like some of my plums have!).
Also make sure they are deseeded !
You can cool the boiled mixture completely but if you'd rather not wait that long , cool for few minutes. Keep whisking as you add eggs so they don't get cooked . Add the flour immediately after the eggs are incorporated.
You can increase the spices to upto 3-4 tsp and use cinnamon , powdered ginger , powdered clove, mixed spice etc.
