Many find fruit cake too dense and heavy. True, a number of fruitcakes are made this way. I have discovered that most commercially made fruitcakes contain too much fruit to batter ratio and this is what makes them so heavy. Added to this is a thick layer of overly sweet marzipan (personally, I'm not a fan of the stuff in any season).
I've been making our family fruitcakes for years. I like to make two types. One with the traditional candied cherries and peel and nuts and dark raisins. The other I make with only the light fruit. Golden raisins, dried citrus peel, dried cranberries and slivered almonds. This mixture gives the cakes a more blonde appearance with the red dried cranberries giving just a bit of colour.
I also separate the egg yolks from the egg whites (trivia question - what is the egg white called . . . besides "egg white"). The yolks get blended into the cream mixture while the egg whites are beaten stiff and then folded in at the end. This makes for a lighter, airier cake.
Another problem with fruitcake is that it can be dry. Good fruitcake remains moist. This comes from properly curing the fruitcake. And this takes time. And brandy. And a dark closet. So I usually start the fruitcakes in mid October.
So here is the recipe our family has used as far back as I can remember.
Wrap each cake with a double layer of cheesecloth. Using extra liquor, brush each cake with enough liquid to dampen cheesecloth. Wrap cakes in aluminum foil and store in a dark closet for 2 to 3 weeks, brushing occasionally with more liquor.
