Here's our plum tree at the bottom of the hill, bent nearly in two from the weight of the plums. They're small this year but profuse.
I cooked them initially in a sugar syrup spiked with lots of vinegar and a pungent bag of cloves and crushed cinnamon sticks. The recipe I followed, a very old french one, called for 30 cloves but I added only 12 or so. In the words of Thomas, the Austrian sous chef at the Danube restaurant in NYC: "too many cloves tastes like too much Christmas." So true, dude.
But I followed the rest of the recipe to the letter. It's a classic fruit confit, or preserve, as we say in English. Boil the syrup, skim it, add the plums and bring to a boil. Remove plums with a skimmer and reboil the syrup to concentrate it. Add the plums back in and leave to steep. Repeat two more times before canning it.
The long slow soaking in the increasingly heavy sugar syrup causes the fruit to absorb the sugar and gradually turn denser and sweeter and almost candied. It's like an exchange between the fruit and the syrup: the fruit absorbs sugar, the syrup takes on the flavor of the fruit. Eventually, they achieve a similar sugar density, which is what makes them safe to keep for a long time.
Ah geez, is this making any sense? It's kind of technical. But all any of us need to know is that this three-day process makes the plums taste really, really good, almost lush: softer but denser . . . sweeter but still tart around the pit.
Sometime this winter I have to make a pate (maybe a coarse one, with duck) so that I can serve these alongside. I wait patiently for the duck hunters who troll our creek in the wee hours on Saturday mornings to feel bad about disturbing our weekend sleep and lob us a duck. In the meantime, I'm going to serve the plums with a lemon pound cake tomorrow for my cooking class. Here's that recipe.
Lemon Yogurt Pound Cake with Pickled Plums
Cake adapted from an old Saveur Magazine
3 sticks butter, plus more for the pan, at room temperature
3 cups flour, plus more for the pan
1 teaspoon baking powder
1/2 teaspoon fine salt
3/4 cup whole milk yogurt
1/4 cup fresh lemon juice
1 teaspoon pure almond extract
1 teaspoon pure vanilla extract
1 teaspoon pure lemon extract
3 cups sugar
6 large eggs, at room temperature
Lemon Syrup:
1/3 cup fresh lemon juice
1/3 cup sugar
Heat oven to 325°. Generously grease a light-colored 10" tube pan with butter. Add 2 tbsp. flour; turn the pan to coat it evenly with flour, tap out any excess, and set aside. (The inside of the pan should be smoothly and evenly coated with butter and flour, with no clumps or gaps.)
Using a sieve set over a bowl, sift together remaining flour, baking powder, and salt. Repeat 2 more times. In a measuring vessel with a pourable spout, combine yogurt and lemon juice and the almond, lemon, and vanilla extracts. In the bowl of a standing mixer fitted with a paddle, cream butter at medium-low speed until light and fluffy, about 2 minutes. Gradually add sugar, 1⁄4 cup at a time, scraping down the sides of the bowl with a rubber spatula, and beat until satiny smooth, about 3 minutes.
Add 1 egg at a time to the butter mixture, beating for 15 seconds before adding another, and scraping down the bowl after each addition. Reduce the mixer speed to low and alternately add the flour and milk mixtures in 3 batches, beginning and ending with the flour. Scrape down sides of the bowl; beat just until the batter is smooth and silky but no more.
Scrape batter into prepared pan and firmly tap on a counter to allow batter to settle evenly. Bake until light golden and a toothpick inserted in center of cake comes out moist but clean, about 1 hour and 15 minutes. Let cake cool in pan on a rack for 30 minutes. Invert cake onto rack.
For the glaze, combine the sugar and lemon juice in a small pan over low heat and cook, stirring, until the sugar melts. Brush the warm syrup on the cake, in two additions, until all of the syrup has been absorbed.
Slice the cake and serve with pickled plums (and whipped cream, if you like).
Pickled Plums
From The Good Cook: Preserving, by Time Life Books, Richard Olney, Editor
Makes about 6 pints
4 pounds slightly underripe plums, each pricked in server places with a needle
8 cups sugar
1 cup water
2 ½ cups vinegar (white or apple cider)
5 cinnamon sticks, broken into small pieces
20 whole cloves
Make a spice bag by placing the cinnamon and cloves in the center of a clean square of cheesecloth, tying up the four corners into a bundle. In a large saucepot, bring the sugar and water to a boil over high heat and cook for about 10 minutes to make a clear syrup. Add the vinegar and the spice bag and boil for five minutes more.
Add the plums and bring the mixture to a boil over medium heat; to avoid breaking the fruit do not boil it hard. Skim.
Remove the fruit from the syrup with a skimmer, then boil the syrup over high heat for five minutes.
Remove from the heat, return the plums to the syrup and allow the mixture to coo. Refrigerate for 24 hours.
The next day, bring the mixture to a boil, remove the plums, boil the syrup for five minutes, return the plums to the pan and let the mixture cool. Let stand another 24 hours. Put the plums into pint jars, cover and process for 20 minutes in a boiling water bath. Store for at least six weeks before using.
