Slowly stir half of the lemon mixture into the 3 egg yolks. Return all egg yolk mixture to saucepan. Cook and stir until mixture comes to a gentle boil. Cook and stir 2 minutes more. Remove from heat. Add butter all at once, stirring until completely melted. Cover surface with plastic wrap. Chill at least 1 hour or for up to 2 days.
