Does alcohol really get cooked out of foods?
With the dawn of St. Patrick's day, quite possibly the booziest day of there year (after New Years Eve of course) I got a little curious about how much alcohol actually cooks out of all those booze infused cupcake recipes I've been ogling over. (If you're curious I will likely be trying my own adaptation to this Tequila Sunrise recipe) It's easy to assume alcohol would, as it's boiling point (173° F) is significantly lower then that of water (212°F)
It didn't take much searching to find out that some ultra-smurt scientists, universities and the USDA were way ahead of my ponderings. In the study they used a variety of alcohols, recipes, and preparation methods, including simmering, sauteing and my favorite of course, baking. So does alcohol really get cooked off during cooking? Well the answer is...Kinda sorta..sometimes...maybe.
Not surprisingly the study concluded that the amount of alcohol retained in food ranged between about 4 and 85 percent. What was surprising was that the amount of alcohol remaining didn't just depend just on how long the alcohol spent above it's boiling point, but the types of foods and vessel size were a primary factors as well. Obviously foods that had alcohol added towards the end of cooking was clocking in at about 75% of the alcohol remaining.
When baked for 25 minutes with the mixture not being stirred, I assume this is where cakes fall into, the retention rate was 45%. ...Those margarita cupcakes you wanted to take to work aren't looking like such a good idea now, is it?
When baked/simmered where the mixture was stirred ( sauces, glazes, syrups, etc) are on average the following:
15 minutes 40%
30 minutes 35%
1 hour 25%
1.5 hours 20%
2 hours 10%
2.5 hours 5%
So...yes the alcohol cooks off, but to my shock not a whole lot of it... Guess my cupcakes won't be going to any AA meetings.
