Gateau Suisse
Author Notes: My mother made this cake for us on special occasions -- it's rich beyond belief, a smooth, silky chocolate extravaganza. I don't know where the recipe came from, or why it's called "Swiss Cake" in French -- but I promise you'll love a thin slice of it, chilled, with a dollop of softly whipped cream or creme fraiche. I've written the recipe here exactly as my mother gave it to me 25 years ago. It's lovely decorated with candied violets or other flowers. - CottageGourmet

@dymnymo: I made this yesterday and it set up perfectly overnight -- I'm wondering, did you use russet potatoes? I used baking potatoes, boiled in their "jackets", put through a food mill, combined with melted chocolate/butter/sugar/egg yolk concoction then smoothed the whole thing into a loaf pan. I'll post a picture later -- sorry you had a problem!

This recipe sounds so good that I will try again.

I made this last night and it did not turn out firm, even after chilling. Since all the ingredients are cooled before adding, does the gateau need to be baked in a water bath before chilling to set the eggs?

I usually keep mine in the freezer because it's so rich -- let me assemble one today and see what happens. I'm so sorry!

Sounds intriguing. What a great photo too. Reminds me of a similar one of my parents.
