Mix 7 tablespoons of the sugar, flour, apple pie spice, and sea salt in large bowl. Add pears, cranberries and almond extract; toss gently to coat. Set aside.
Roll dough between 2 pieces of parchment paper into a 12" circle. Place dough onto parchment paper-lined baking sheet. Spoon filling into center of dough, spreading to within 1 1/2" of edges. Fold edge of crust up over fruit, pleating or folding crust as needed. Brush crust with beaten egg and sprinkle with remaining 1 tablespoon sugar and sliced almonds.
Bake the crostata on the middle rack of the oven 25 to 30 minutes or until pears are tender and crust is golden brown. Cool slightly on baking sheet. Cool completely on wire rack. Serve with ice cream or whipped cream, if desired.
