Cooking School: Apple Kuchen

There are many, many varieties of dessert that claim the name kuchen, from yeasted pastries to custard and fruit-filled pies. At its core, though, kuchen is simply the German word for "cake" and none of the delightful baked goods associated with it are misnamed.
This recipe is published in the French Laundry Cookbook - the gorgeous tome dedicated to the works of Thomas Keller - but I picked it up some time ago on the Amateur Gourmet's site. The original version adds blueberries and has a slightly different spicing, though I really love the combination I used here. Mine has cinnamon and vanilla, in addition to nutmeg. The nutmeg really shines in this dish and I strongly recommend using freshly ground.
The unusual thing about this cake is that the batter is thick and stiff. It doesn't fill the pan completely in its unbaked state, but rises high around the apples as it bakes. The kuchen is beautiful to look at. After it has cooled, the cake will shrink back from the apples slightly, so don't be suprised when it happens.
Apples seem to pose a challenge to many chefs who don't like the fact that they begin to brown as soon as you have sliced into them. Don't bother tossing them in lemon juice or any other slightly acidic solution. The apples will brown in the oven, so it's not necessary to try to prevent browning before they are cooked. In fact, a browner appearance to the fruit will probably be more appealing the the final dish. I used a combination of Fuji and Pink Lady apples for this kuchen. I think that a sweeter apple is a much better choice to compliment the light sweetness and spicing of the cake than a tart Granny Smoth-type apple.
The kuchen is best served warm, so slice it after cooling only for a short time or let it cool completely and reheat each portion in the microwave. I think it tastes just as good, perhaps better, on the second day. Top each warm piece with a dollop of whipped cream or a small scoop of vanilla ice cream, if desired.
