Lemon Curd

Directions

1. 1
   Combine egg yolks, egg and sugar in a double boiler (or just place the ingredients in a heat-safe bowl and place the bowl over a pot of boiling water, making sure the bottom of the bowl is not touching the water - it's the steam that does the cooking).
2. 2
   Mix well.
3. 3
   Stir in lemon zest, lemon juice and margarine.
4. 4
   Cook over simmering water, stirring constantly, for 10-15 minutes or until the mixture thickens.
5. 5
   Remove from heat; cool.
6. 6
   Use when cooled or spoon into a container and cover tightly.
