Here's a good idea for your St. Patrick's Day dessert
I just came back from Vegas (didn't see ronjohn ) and had my favorite dessert (bread & butter pudding with whiskey cream sauce) at my favorite place there (http://www.ninefineirishmen.com/)
I found pretty much the same thing here: http://www.kevindundon.com/bread_and_butter_pudding.html
The only difference is that once the custard sauce is cooled, add (to taste) some Bushmill's whiskey.
