Nonsense Cake

California is a pretty dry place, and though we've come out of our latest drought rather spectacularly, with heavy rainstorms and fog and wet well into the summer, the weather is still rather mild compared to, for instance, Philadelphia. Which is where I was this year as Californians complained about their dreary storm clouds, sopping rain puddles, and thick, lovely snowcaps. Happy as I was to miss the excitement and return to a much better watered state then when I left, I haven't completely avoided the unpleasant side-effects of our return to more sustainable waterways. Because, you see, our delicate agriculture that California so lovingly cultivates was affected by the unusual bounty of rain. Our more sensitive fruits – tomatoes, peaches, strawberries, cherries – have not only been late this year, but less intensely flavorful, less ripe, and far less plentiful. Except the plums.

The plums have been pretty fantastic.

And my mum, who 99% of the time would prefer a fresh piece of fruit over any confection that even the very best local, organic, unionized, free-range bakers might produce, has a deep, uncharacteristic love of zwetsche kuchen, a sort of German breakfast cake where a soft, sweet, spongy dough is generously covered in plums and baked until each plum piece is surrounded by a puffy golden pastry. And my mother is a damn good cook, so when plum season comes around, my mother stocks up on the little purple-green prune plums in the hopes that she'll end up with too many and be forced to bake them.

The recipe is from my great aunt Eva who, despite our family's legacy in the kitchen, was a fantastic cook in her day. My mother, as a child, tried to request Eva's zwetsche kuchen in her informal, phonetic German, and instead asked for schwatzen kuchen – nonsense cake – sending her aunt into hysterics, and providing one of the few family anecdotes about food that actually results in something delicious.

Eva calls for three to four pounds of fresh prune plums, which is about as many as you can possibly fit into your pie pan, plus a few more.

Unlike many German desserts, this cake is primarily about the fruit, not dark spices or rich pastry. It's a summer cake, and the plums should be nearly stacked on top of each other so that even when they shrink in the oven there will be hardly any room for the pastry to puff up around them.

But it is still a German cake, so the plums are lightly sprinkled with sugar and breadcrumbs – or, in our case, leftover ground hazelnuts – before they go in the oven.

In the oven the cake expands, turning golden and crispy around the edges, and the plums become soft and dark. Served hot, the crumbly warm cake sets off each bite of wet, thick plum. Left to itself for awhile, the flavors deepen and the plums imbue the cake with their juices.

My personal preference is to eat it hot right out of the oven it for dessert, and then, after it has sat overnight, again for breakfast the next morning.
