@FrogPrincesse Here’s a crumb shot, it’s very fine textured, thin crust and because it’s so good this way, I have never made it with butter. I make it entirely in the food processor.
i imagine it would be very good using butter and as written by Roddy, that is how it was made, I hope you try it either way!
I warm up some jam, add a little liqueur of choice and brush it on the outside of the cake, then sprinkle with confectionery sugar.
