Use an electric mixer and beat the egg yolks until they are thick and turn to a light yellow, don't over mix. Turn the mixer off and add the sweetened condensed milk. Turn speed to low and mix in half of the lime juice. Once the juice is incorporated add the other half of the juice and the zest, continue to mix until blended (just a few seconds).
