Wild plum pie is Wyoming's best-kept secret. While the county fair blue ribbons go to apple and cherry, the old-timers know the truth: nothing captures the taste of late summer on the high plains like these small, fiercely flavored fruits gathered from thickets along creek banks and ranch fence lines.

The Prunus americana has fed people on this land for thousands of years. The Arapaho and Shoshone dried them for winter. When homesteaders arrived in the 1870s and 1880s, ranch wives learned quickly that these wild plums, too sour to eat raw, transformed into something extraordinary when baked with sugar between layers of pastry. A good pie became currency. It could thank a neighbor for help with calving, welcome a new family to the valley, or win a man's heart at a church social.

The fruit ripens in late August through September, hanging in dense clusters that glow amber and ruby against dusty green leaves. You'll find them along irrigation ditches, creek bottoms, and the edges of cottonwood groves where cattle gather for shade. Bring buckets. The trees produce abundantly, and once you've tasted this pie, you'll want enough fruit to freeze for winter baking.

The crust matters as much as the filling. Lard was the fat of the frontier—rendered from the hog butchered each fall—and it produces a flakier, more tender pastry than butter alone. I've given you both options. Use what your grandmother would have used, or what you have in your kitchen. Either way, you're making something worth the effort.

The technique, the tradition, and the story behind every dish.

Equipment Needed

  • Pastry blender or two butter knives
  • Rolling pin
  • Rimmed baking sheet
  • Wire cooling rack
  • Pastry brush

Instructions

  1. 1

    Make the pastry dough

    Whisk together flour, sugar, and salt in a large bowl. Add the cold lard or butter cubes and work them into the flour using a pastry blender, two knives, or your fingertips. You want pieces ranging from pea-sized to the size of small lima beans. This unevenness creates flaky layers. The mixture should look shaggy and dry, with visible chunks of fat throughout.

    If using your hands, work quickly. Warm hands melt fat, and melted fat means tough pastry. Dip your fingers in ice water to keep them cold.
  2. 2

    Bring the dough together

    Combine vinegar with six tablespoons of ice water. Drizzle over the flour mixture while tossing with a fork. Add water one tablespoon at a time until the dough just begins to clump when you squeeze a handful. It will look dry and ragged. This is correct. Divide the dough in half, shape each portion into a flat disk about one inch thick, wrap tightly in plastic, and refrigerate for at least one hour or overnight.

  3. 3

    Prepare the wild plums

    Pit the plums by slicing around the equator and twisting the halves apart, then popping out the stone with your thumb. Wild plums cling to their pits more stubbornly than their cultivated cousins. Some will tear. This is fine. Leave the skins on. They hold pectin and color, and their slight chewiness in the finished pie is honest. You should have about four cups of fruit.

    If you find plums with particularly tough or bitter skins, blanch them for thirty seconds in boiling water, then slip the skins off. Most wild plums don't require this.
  4. 4

    Make the filling

    Whisk together the sugar, flour, cornstarch, cinnamon, nutmeg, and salt in a large bowl. Add the prepared plums and lemon juice, tossing gently to coat every piece. Let this mixture sit while you roll out the crust. The sugar will draw juice from the fruit, creating the syrup that thickens into that glossy, spoonable filling.

  5. 5

    Roll out the bottom crust

    Remove one disk of dough from the refrigerator and let it soften for five minutes. On a floured surface, roll from the center outward, rotating the dough a quarter turn after every few strokes. Work quickly and confidently. You want a circle about twelve inches across and roughly one-eighth inch thick. Drape it over a nine-inch pie plate, easing it into the corners without stretching. Leave the overhang for now.

  6. 6

    Fill the pie

    Pour the plum filling into the crust, mounding it slightly higher in the center because the fruit will settle as it bakes. Scrape in every drop of the accumulated juice. Scatter the cold butter pieces over the top. These will melt into the filling, adding richness and helping the top crust release steam.

  7. 7

    Top and crimp

    Roll out the second disk of dough to the same dimensions. Drape it over the filling. Trim both crusts to a one-inch overhang, then fold the edges under themselves, creating a thick rim that rests on the lip of the pie plate. Crimp decoratively by pressing with a fork or pinching with your fingers. Cut four or five slits in the top crust to let steam escape.

    For a lattice top, cut the second crust into strips and weave them over the filling. The exposed fruit caramelizes beautifully, and the presentation is pure county fair.
  8. 8

    Apply egg wash and chill

    Brush the entire top crust and crimped edges with egg wash, working into every crevice. Sprinkle generously with coarse sugar. Place the assembled pie in the refrigerator for twenty minutes while you preheat the oven to 425°F. This final chill firms the fat, ensuring maximum flakiness.

  9. 9

    Bake the pie

    Set the pie on a rimmed baking sheet to catch any drips. Bake at 425°F for twenty minutes, until the crust turns light golden and the kitchen smells of butter and warm fruit. Reduce the temperature to 375°F and continue baking thirty to thirty-five minutes more. The pie is done when the crust is deep golden brown and thick juices bubble actively through the vents. You should hear the filling simmering.

    If the edges brown too quickly, shield them with strips of aluminum foil or a pie crust guard for the final fifteen minutes.
  10. 10

    Cool before slicing

    Transfer the pie to a wire rack and resist temptation for at least three hours, preferably four. The filling needs time to set. Cut into a hot fruit pie and you'll have delicious soup. The patience is worth it. Serve at room temperature or barely warm, with a scoop of vanilla ice cream, a pour of cold heavy cream, or a wedge of sharp cheddar if you follow the old Wyoming custom.

Chef Tips

  • Wild plums vary tremendously in tartness depending on the tree, the season, and when you picked them. Taste your fruit before measuring sugar. Very sour plums may need up to a quarter cup more. Sweeter fruit, less. Trust your palate.
  • If wild plums are unavailable, substitute Italian prune plums, damson plums, or a combination of red plums and sour cherries. The flavor will differ, but the spirit remains.
  • Lard produces the flakiest crust, with a subtle savory note that complements fruit. Look for leaf lard from a butcher or farmers' market. Hydrogenated supermarket lard is not the same thing. If using butter, freeze it solid and grate it on a box grater for easier incorporation.
  • This pie travels well. Ranchers' wives have been hauling it to potlucks and church suppers for a hundred fifty years. Bake it the morning of your event and transport at room temperature.

Advance Preparation

  • Pie dough can be refrigerated for up to three days or frozen for two months. Thaw overnight in the refrigerator before rolling.
  • Wild plums freeze exceptionally well. Pit and halve them, spread on a sheet pan until frozen solid, then transfer to freezer bags. Use directly from frozen, adding ten minutes to the filling maceration time.
  • The finished pie keeps at room temperature, loosely tented with foil, for two days. After that, refrigerate and rewarm slices in a 350°F oven for ten minutes to restore crispness to the crust.
