I did this early in the month. I had never made a yule log before, I had never made buttercream, genoise cake or Meringue mushrooms so this month was an adventure.
I started with the mushrooms, they looked to be the easyst to put
I put them aside in a plastic bag for a few days, I needed at least one whole day to make the cake.
Well the genoise cake was interesting, I am not sure if it came out right. It tasted ok and rolled so I went with it.
I however had troubles with the buttercream. It kept breaking and curdling. I finally got it so that it did not look that bad. I think that part of my problem was that room temp was not warm enough for my butter. I keep my house cold in the winter. I got the rolled cake fine but decorating it was a puzzle to me. I have not seen many yule logs before. So I just put mushrooms everywhere. I then wrapped the whole thing up and took it to work. It was way to sweet for me. They ate it.
