I use the bero book recipie with added caveats...
Firstly no marg/lard/post war deprivation whatever. BUTTER.
Secondly, fruit wise i put in other tasty stuff, cranberries, apricots, barberries, prunes, crystalised ginger, whatever.
Thirdly i use part caster sugar, part dark muscavado.
Fourthly, no ground almond dust buy whole ones, pop them in boiling water to slip the skins off, stick them in the blender, but not too fine.
Fifthly (and then i'll stop banging on) lots of booze. Soak the fruit in it, pour it over when the cake is hot out of the oven (mmm, that smell alone makes it all worth while) and more over the coming weeks.
Oh, and sixethly, use about four times the spice...of my own secret blend. 
Oh, and one more, i use sr flour, or some baking powder. It doesn't rise too much, but with all that fruit a slight openness to the crumb helps.
Eat with wensleydale.
