Help needed from my FODMAPS-challenged friends.

I know a bundle of you have various dairy issues. I want to make a couple of "thank you" fruit cakes for a pair of lasses who have the FODMAPs issues. I know that means no dairy or flour, but I'm finding conflicting information about dried fruit. Also, I know they have to avoid large amounts of alcohol, but some? In reality, although the cake tends to reek of brandy, there isn't more than about 2 measures in a whole cake.

It needs to be a cake or something else that can stand being posted.

So, here are the ingredients:

Non-wheat non-gluten flour
Dairy-free butter substitute
Assorted spices (cinnamon, nutmeg, ginger)
Sultanas and currents (I'll avoid the glace cherries)
Eggs
Sugar
Brandy (approx 100mls in a 2 kg cake, so very little per slice)

Are they ok? Should I substitute something else?
