3/4 cup sugar
4 eggs
1 (14-oz) can condensed milk
1 (12-oz) can evaporated milk
1 teaspoon vanilla

Fill a broiler pan with water and place on bottom shelf of oven. Heat oven to 350°. In a saucepan, over medium heat, heat sugar while stirring constantly until it reaches a carmel color. In blender, add eggs, both cans of milk and vanilla. Pour sugar mixture into flan pan, followed immediately by milk mixture. (This is crucial!) Blend. Place pan on upper shelf of oven and bake for 25-30 minutes. Cook until almost firm and brown on top. Let cool for about 10 minutes. Use rubber spatula and loosen around all sides. Flip it over onto serving platter and chill.
