1/2 c. evaporated milk
1 tbsp. white vinegar or lemon juice
3/4 c. yellow cornmeal
1/4 c. all-purpose flour
1 tsp. baking powder
1 1/2 tbsp. sugar
1/2 tsp. salt
1/4 tsp. baking soda
2 1/2 tsp. chilled Crisco

Stir together evaporated milk, vinegar and 1/2 cup lukewarm water and let mix stand, covered in warm place 1 1/2 hours.

In another bowl sift together cornmeal, flour, baking powder, sugar and soda. Grease cast iron skillet 6 1/4" across top and at least 1" deep with 1 teaspoon Crisco and heat in preheated 450 degree oven for 10 minutes. Add remaining 1 1/2 teaspoons Crisco to cornmeal mix and blend until resembles fine meal. Stir in slowly 2/3 to 3/4 cup milk, mix, adding enough to form batter that barely holds shape on spoon. Don't overmix. Pour batter into hot skillet and bake in middle of 450 degree oven for 10 to 12 minutes or until skewer comes out clean.
