Recipe
Preheat oven to 350 degrees.
Prepare dough: In a mixing bowl fit with a paddle, mix butter and sugar until they come together, allowing some lumps to remain. Add yolk and mix until combined. Add flour and mix until smooth. The dough will be crumbly at first but will hold together. Turn out onto plastic wrap, flatten into a disc and, if very soft, chill until firm. Roll out to 1/4-inch thickness and fit into a 10-inch tart pan or press with fingertips directly in pan (you will have extra dough). Bake tart shell for 15 to 20 minutes, or until lightly colored. Set aside to cool.
Prepare filling: In a medium bowl, combine sour cream, sugar, flour, egg, vanilla and salt. Add pears and toss gently to coat. Spoon pear mixture into the tart shell, mounding pears slightly in the center.
Prepare streusel: In the same mixing bowl used for crust, combine the butter and sugars. Mix until crumbly. Gradually add flour and mix until incorporated. Add oats and mix until combined. Top pear mixture with streusel (you will have extra streusel). Bake for 35 to 45 minutes or until streusel and crust are golden.
