Fry 2 glasses grated stale roll crumbs in 1 spoon melted butter, pour on 1 glass boiling hot table wine, and mix until smooth. [In a separate bowl], beat 1 spoon butter until white and mix with 6 egg yolks, 3 spoons fine sugar, and cinnamon. Combine the eggs and sugar with the roll crumbs, add 6 beaten egg whites, transfer to a mold, and bake.
One wineglass rum may be added, in which case, use a little less wine. Pour on rum sauce.
