Fresh Lime Curd

Directions

1. 1
   Place the sugar, butter, lime juice, lime zest in the top of a double boiler; stir over medium-high heat until butter melts. Mix 2 tablespoons hot lime mixture into the eggs and stir to blend.
2. 2
   Reduce heat to medium until water simmers. Slowly whisk egg mixture into the lime mixture. Cook over the double boiler until lime mixture thickens and coats the back of a wooden spoon, 20 to 25 minutes. Cool slightly and spoon into a clean, glass jar. Cover and refrigerate.
