Beat the eggs and sugar with a whip attachment until light and thick. Scald the milk in a double boiler. Gradually add in the milk to the egg mixture with the mixer on low speed, being careful to add the milk slowly as to not curdle the egg. Pour the mixture back into the double boiler and heat to 185 degrees Fahrenheit (but not over 190 degrees Fahrenheit). Remove from heat and set in pan of cold water to cool. Add the vanilla and orange zest and stir occasionally to cool evenly. Excellent over Orange Bread Pudding.
