Plum Crumb Flan
2 cups All-purpose flour
1/4 ounce Dry yeast
1/4 cup Sugar
cup Milk, heated, 115 degrees
6 tablespoons Butter, melted
1 pinch Salt
Zest of 1 lemon
Zest of 1 orange
3 pounds Italian plums (purple plums)*
1 1/4 cups All-purpose flour
1/4 cup Dark brown sugar
1/4 cup Granulated sugar
1/4 teaspoon Ground nutmeg
1/2 teaspoon Ground cinnamon
4 ounces butter, cut into small squares
Sift flour into a bowl and make a well in the center. Place yeast and 1 tablespoon sugar in the well. Add the milk and stir to dissolve the yeast mixture. Cover the bowl and set aside for 20 minutes.
Add the melted butter, egg, salt, lemon and orange zests and remaining sugar. Stir the mixture to make a soft dough. Turn out dough onto a lightly floured surface and knead until smooth and elastic. Place dough in a greased bowl and cover. Let rise until doubled in size, 1 to 1 1/2 hours.
Punch down dough and roll or pat it to fit a greased, 15-by-12-inch jellyroll pan. Cut the plums in half and place them on top of the dough in rows, overlapping the fruit if necessary.
Prepare the topping by combining the flour, sugars and spices in a bowl. Add the butter and stir until the mixture resembles coarse crumbs. Sprinkle topping evenly over the plums. Set aside to rise for 30 minutes.
Heat an oven to 375 degrees. Place jellyroll pan in the center of the oven and bake for 30 to 35 minutes, or until plums are soft.
