I had no idea there was alcohol in it. I noticed when I tasted it, but it was only in a small amount of the desert.I have suffered no ill effects and I do not have a desire to drink, nor did I at the time of consumption.
I will not go out of my way to order foods with alcohol, but if something like this happens again I think it won't bother me too much. That being said for at least the next 90 days to a year I won't be having tiramasu.
