Place dough on baking sheet.
Combine plums and cornstarch in a large bowl, tossing to coat.
Add 1/4 cup Plum Jam; toss well to coat. Arrange plum mixture on top of dough, leaving a 1 1/2-inch border. Fold edges of dough over plum mixture.

Remove galette from oven (do not turn oven off).
Brush crust with 1 tablespoon Plum Jam; sprinkle galette with sugar.
