haven't read links but got impression it not possible :( Which is a great shame, because a particular favourite of mine, the Manchester Tart, is only available sporadically :(
So do I murray. But I'll be making an Angel Food Cake in the future so will have about 10 egg yolks left over and thought I'd make some chocolate custard for the freezer. Probably have to make lemon curd now. D'ya reckon lime curd would work the same way as lemon? I never see it about.
