1/2 t smoke sea salt
2 sticks frozen butter, cut into little cubes
1/4 C sour cream
1/2 C ice-cold water
1/2 t cinnamon
Place flour, salt and butter in a large mixing bowl; with a pasty cutter, cut butter into the flour and salt mixture until it resembles coarse sand. In another bowl, whisk together sour cream, water and lemon juice. Slowly drizzle in the liquid mixture to the flour and butter, blending just until a rough ball forms. Pour out onto a lightly floured board and knead until just combined. Pat dough into a ball, wrap in plastic and refrigerate for one hour.
Meanwhile make apple filling. Melt butter over medium heat in a large skillet. Add apples and sauté for 3 minutes or until beginning to soften slightly. Add cinnamon and raw sugar. Cook for 2 minutes more, or until raw sugar melts. Remove from heat and cool completely.
