Crust:
1/2 cup flour (whole wheat, whole wheat pastry, white wheat, or oat flour)
1/2 cup rolled oats
1/2 tsp. salt
1/4 cup cold butter, cubed
2 Tbls. cold water
Stir together the flour, oats, and salt. Cut in the butter until it's clumpy. Stir in the water. Put dough on a piece of plastic wrap and use the wrap to press it into a ball, then chill.
Preheat oven to 350 F.
Meanwhile, make the filling:
2 1/2 cups almond flour
1 cup quince jam
2/3 cup dried or candied fruit, finely chopped
1 tsp. cinnamon
2 egg yolks
1/2 cup sour cream
Mix all ingredients together.
When the crust is firm to the touch, place the ball of dough in a pie tin. Use the plastic wrap as a shield to roll or press out the dough to shape the crust in the pie tin. Press the filling evenly into the crust.
Bake at 350 for 30 minutes.
I based this on a medieval recipe for a quince tart that called for quinces preserved in sugar. I figured that was pretty much the same as quince jam, which I found at a Mexican market, in the refrigerated section near the yogurt, pudding, and flan. Hopefully you can find some. I figured it was the closest to real quince I'd ever find.
For the dried fruit, I used whole raisins, whole currants, and chopped prunes.
