many years ago i was given the recipe for a mandarin gateau that had a sort of buttercream filling which contained raw egg. i didn't find the piece of paper it was written on when clearing my mother's house ( when i lived there it lived between cookbooks - hahaha - on the morning room mantle shelf) although i looked carefully for it.
i've found a recipe nearly similar online but that instructs you to make a syrup with the sugar and add it to raw yolks while still hot. my recipe wasn't made with hot syrup, and was more like sponge mix before the flour is added.
the thing is i can't remember if it was whole eggs or just the yolks, although i think i come down on the whole egg side.
if anyone has the recipe (from the mid seventies) i would be very grateful.
