Pre-heat oven to 350 degrees and prepare a 9-inch-baking pan, lined with parchment paper and buttered and sprinkled with flour.
Sift together flour and cornstarch in a small bowl.
In the bowl of stand mixer, beat egg yolks and ¾ cup sugar with whisk attachment for about 5 minutes, until thick and pale. Remove mixture to separate bowl and clean stand mixer bowl.
In the stand mixer bowl, add egg whites and salt. Beat on medium speed until you get soft peaks. Turn mixer to low and add ¼ cup sugar, continuing to beat until whites are stiff, 1-2 minutes more.
Carefully fold the egg whites into the egg yolks. Then fold the flour/cornmeal mixture into the eggs.
Pour batter to cake pan, smoothing the top. Bake at 350 degrees for 30-35 minutes, until cake tester comes out clean. Let cake cool in pan for a few minutes before removing to rack to cool completely.
Once cake is cooled, use cookie of biscuit cutters to cut small circles that will fit in 5 oz. parfait glass. You will need 24 small rounds.
