This lemon curd is one part of a several-day project. There are parts of the cake which I am going to bake can be made days ahead. I usually try avoiding making things that ask to cook or heat lemon/lemon juice because I am not fond of damaging the Vc in the lemon. But this cake calls for lemon curd as the cake filling. So at least once in my life time, I will have to make this curd. The process is very easy, nothing can complain. It's very tasty, just not comfortable with destroying Vc. Recipes are available but I used this one.
