Wow. I am on a lowish carb diet and those sound perfect.
I would also add a friend's fruit cake which does have flour, but very little, no egg, no fat, no sugar. It tastes a bit like an extremely fruity bread pudding and of course it does have loads of dried fruit, but it lasts for ages and you only need a thin slice.
Sugar free Fruit Cake
6 0z flour
3 teaspoons Baking powder
2 oz ground almonds
2 teaspoons Mixed Spice
1 lb mixed fruit
4 0z Dates
4 oz dried apricots
grated rind of an orange
1/2 pint of water (alcohol if required added to make up the water)
2 tablespoons of Orange juice
Soak fruit over night in liquid
Add dry ingredients and stir well
2 lb loaf tin. for 1 and 1/2 hours at 160 c. Cover for the last hour.
Freezes well too.
Can use any combination of dried fruit that you choose.
I add lots of cinnamon and nutmeg and glace cherries and stuff at xmas to make a healthier xmas cake, with alcohol and orange juice instead of water.
Maybe the flour could be reduced and more ground almonds substituted, I shall have to try that.
