Lemon Curd

Directions

1. 1
   Whisk the lemon juice, sugar, and eggs together in a double boiler over simmering water, then stir continuously until the mixture begins to thicken; this could take 10 to 15 minutes.
2. 2
   As soon as the mixture thickens, add the butter and stir until it melts.
3. 3
   Remove the lemon curd from the heat and continue to stir until the butter is fully incorporated.
4. 4
   If its lumpy, push it through a fine-mesh sieve to smooth it out.
5. 5
   Lay a piece of plastic wrap directly on the surface of the curd and set it aside to cool.
