Masa harina is a flour made from corn. It is not the same thing as corn meal. You can find it in the baking or Hispanic section of your grocery store.
SWEET CORN PUDDING
1/2 cup butter (1 stick), softened
1/3 cup masa harina (Mexican corn flour)
1/4 cup water
1 1/2 cups frozen corn, thawed
1/4 cup cornmeal
1/3 cup sugar
2 Tbsp. heavy cream (or milk can be used)
1/4 tsp. salt
1/2 tsp. baking powder
Preheat oven to 350 degrees. In a medium bowl beat together the softened butter, masa harina, and water until well mixed. Using a food processor or blender, process the thawed corn, but leave it a little chunky. Stir into the butter mixture. Add cornmeal, sugar, cream, salt, and baking powder and stir to combine. Pour batter into an ungreased 8x8 baking pan. Smooth batter and cover pan with foil. Place pan into a 9x13 baking dish that is filled 1/3 of the way with water. Bake for 50-60 minutes. Allow to cool for 10 minutes before serving.
