1/2 cup sugar
1 12 ounce can evaporated milk
1 14 ounce can sweetened condensed milk
1 tsp. vanilla
Prepare large skillet by filling in halfway to the top of the skillet with water. Place utility rack on the lip of the skillet. Bring water to a boil over medium heat.
Make caramel in a small saucepot by melting the sugar at medium heat. Stir until sugar turns light brown. Pour the melted sugar into double boiler inset, quickly turning pan so caramel covers the bottom.
In a blender mix the evaporated milk, sweetened condensed milk, vanilla and eggs. Pour this mixture on top of the caramel in the double boiler inset.
Place double boiler from the utility rack. Run a knife around the edges of the flan and turn onto a large plate. If the top of the flan seems to have excessive moisture, blot it off with a paper towel.
