10 egg yolks
1 can condensed milk (not evaporated)
1 (5 fl. oz) evaporated milk
5 oz. water
Rind of 1 lime, grated
1/2 c. sugar

Using a deep baking pan, caramelize the sugar in the pan, coating all sides. Cool. Mix egg yolks, condensed and evaporated milk and water, using a fork. Strain through a cheese cloth and pour into prepared pan. Sprinkle grated lime rind on top.

Using a deep kettle, bring 5 cups water to a boil, place a wire rack on the bottom, carefully place filled baking pan and steam for 1 hour. Make sure water doesn't go over the custard but just barely touching bottom of baking pan. Cool. Carefully turn over onto serving dish.
