Cornmeal Crust: makes 2
11 oz. All Purpose flour
3 1/2 oz. yellow cornmeal
2 tsp. sugar
1 1/2 tsp. salt
2 sticks cold unsalted butter, cut into pieces
1/3 cup crema or sour cream
1/4 cup ice water
Put all dry ingredients in a food processor and pulse to combine. Add butter and pulse until the mixture is coarse and pebbly. Move to a bowl. Work in crema and water to form a dough. Divide into 1/2, chill for 4 hours to overnight. Remove from fridge and roll out like pie crust, lining a pie pan.
This dough freezes well, we always make one onion tart and freeze the other crust for later.
