A rustic free-form tart with seedless Concord grape filling inside a crisp cornmeal crust.
Don"t skip the slip-skin step — it"s the difference between a galette with real texture and one full of seeds. If the filling looks very loose after sieving, simmer it a couple minutes longer before mixing in the skins, but don"t cook it down all the way; it thickens further in the oven. Frozen Concord grapes work well and are actually easier to skin after a partial thaw. Leftovers keep at room temperature, loosely covered, for up to 2 days, or refrigerated for up to 5.
