Lime Mousse

Directions

1. 1
   Melt butter in microwave.
2. 2
   Beat eggs and sugar in bowl until light and foamy. Add mixture to melted butter. Cook gently, stirring CONSTANTLY, until mixture becomes a custard, about 8 minutes. Do not overcook, or eggs will scramble.
3. 3
   Remove custard from heat and stir in lime juice and zest. Cool to room temperature.
4. 4
   Whip cream until VERY stiff; almost the consistency of butter. Stir lime mixture into cream until just incorporated. Pour into a serving bowl and let chill for at least 4 hours.
