This question came up with a friend of mine who tries to avoid alcohol: should I be eating those boozey cupcakes? I did a little research and stumbled across this site, which is where I got the chart below. I'm not sure how scientific this is, since other factors like percentage of alcohol you're starting with (are you making a wine reduction sauce or dousing a bread pudding with Grand Marnier?), cooking/baking temperature and what other ingredients you're using could affect the outcome, but this chart probably gives us a general idea.
By the way, I should throw this out there while our relationship is fresh and exciting: I'm a nerd. I studied economics in college and I really love charts and graphs.
I probably should also throw this out there: Ellen is a nerd. An incredibly awesome, stylish & savvy nerd. And, I've discovered that baking with scientists = ridiculously fun. It's kind of like baking with Alton Brown. Ellen can explain the chemical reactions of various ingredients and decode trade secrets like nobody's business. And she throws a mean dinner party too - more on that later!
