Zwetschgendatschi or German Plum Cake

Zwetschgenkuchen5

I first heard of Zwetschgendatschi when NPR did a Found Recipes piece on pastry chef and author Gesine Bullock-Prado (also the sister of Sandra Bullock). Bullock’s father was American, but her mother Helga was a German opera singer. She talks about how difficult it was for her to make this cake after her mother died. It was powerful to read this, and I have seen something similar while collaborating with ladies on this blog about their own family recipes: Sometimes sharing is easy for them, they’re excited to share, and excited to talk about their family dish, but sometimes it’s very difficult. Memories are baked into food and can bring up surprising emotions if you’re not ready for them.

This particular dish, Zwetschgendatschi, is sometimes called “Summer Cake.” The cake is traditionally made with Damson plums, which are tiny, dark purple, oblong plums that only ripen for a few weeks a year around August. This plum is slightly more tart than most plums you will find in the grocery store.

When made in sheet cake form, it is more pie or tart than cake. An alternate version calls for a yeast dough with no streusel on top. Whichever recipe is used can give you a good idea where someone is from in Germany. In parts of Central Germany it is known as Quetschekuche, while in the western region it’s known as Prummetaat, and in Bavaria or Austria it is more often known as Zwetschgendatschi. The people in Augsburg, in Bavaria, claim to be the creators of the recipe. The city’s nickname is “Datschiburg” in reference to the cake, and the arrangement of the plums on top of the cake are said to resemble the pine cone on the city’s coat of arms. Their version uses a shortbread crust, which is what I used here.

Zwetschgendatschi
Makes one 8″ tart. Slight variation on this recipe from NPR.

Ingredients:
For crust:
1 1/4 cup all-purpose flour
1/4 cup cornstarch
1/4 cup, plus 1 tbsp sugar
1/2 tsp salt
3/4 cup unsalted butter, cubed and very cold (1 1/2 sticks)

For filling:
1 egg yolk
1 tbsp whole milk
1 tsp vanilla extract
About 10-14 small-to-medium plums (Damson, or Italian Prune Plums)

For topping:
1/8 tsp nutmeg
1/4 tsp cinnamon
1 tbsp sugar

Instructions:

Whisk together the egg yolk, whole milk, and vanilla. Set aside.

In a food processor, or large bowl, combine the flour, cornstarch, sugar, and salt. If using a food processor, add the butter to the bowl and process until the butter pieces are a bit smaller than pea-sized. If using a bowl, cut the butter into the flour mixture. Add the egg yolk mixture slowly. Process or mix with your hands until the mixture just begins to stick together. It will still appear crumbly.

Pour out the mixture onto a lightly floured surface. Pull the mixture together, kneading until all the dry parts are combined. Form into a disc, wrap in plastic, and refrigerate for 30-45 minutes.

Preheat oven to 350 degrees.

Remove the pits from the plums, and quarter. Set aside.

Using your fingertips, press the dough into a 8-inch tart pan. Reserve a golf ball sized portion of the dough to sprinkle over the top.

Arrange the plum quarters over the top of the tart. Crumble the remaining dough and sprinkle over the top.

Mix together the nutmeg, cinnamon, and sugar. Sprinkle mixture evenly over the top of the plums.

Bake for 35-45 minutes, until the plums are very tender.

Allow to cool completely and then enjoy!

This cake can be made with other varieties of plums, but make sure they are not overly ripe, which would make them very sweet and too juicy. Italian prune plums are a good alternative to Damson plums, if you can find them. (Prune plums are what I used for this recipe.) I relied on the recipe given by NPR, but I did find a recipe in a newspaper from the 1980’s that suggested adding a little nutmeg and cinnamon to your sugar mixture to sprinkle over the top, and that seemed like a heck of an idea. While it looks a little oozy in the photos above, that does not do it justice. The smooth, buttery shortbread crust holds up wonderfully against the juicy fruit.

I hate to tell you this, but summer is almost over. Now is the time for summer cake! Do it for the season.

One final thought: It always seems strange to be writing about food with everything happening in the world. I’m baking and researching history as a way to work through and try to understand what’s going on in our country, and how I can help. I’m mad, and appalled, and disappointed. We owe so much to the diversity that built this nation. Every recipe that I feature on this site is influenced by countries and peoples from around the world. I have said before that I wish to generally keep politics off this food history blog–it’s supposed to be fun and delicious, you know. However, humanity is not political, and this argument is not about liberals or conservatives, it’s about our fellow humans. We are all equal. It seems elementary to say but, it turns out, some people still don’t understand the concept. If you don’t agree, I don’t expect any of my posts about border-crossing recipes to make any sense to you. For everyone else: Let’s bake together.
