When baking/cooking, at what temperature does alcohol burn off?

The boiling point of alcohol is 172 F having said that , that number is meaningless because there will always be some alcohol left in the product.

From a practical point of view the residual alcohol is negligible. Realistically speaking mouth wash contains a lot more alcohol But the residual alcohol does present an ethical dilemma.

If you're having a dinner party and one of the couples are members of the Mormon Church you cannot tell them in good conscience that the Bordelaise Sauce that's been reducing for the past 20 minutes has no alcohol in it, because it does.

Well the truth of the matter is the alcohol content will never burn off completely, just a significant majority of will dissipate. Normally alcohol will begin to evaporate when it comes in contact with any heat source equivalent or less than 20 degrees below boiling point. But for cooking purposes, the boiling point is when the alcohol will begin to burn off. Now how can you tell, well that is a bit more difficult to answer. If you are dealing with a substance with a high alcohol content (80 proof or higher), the alcohol will flare up in the pan causing a slight fire. Well, when the fire dies down on its own, that is when the majority of the alcohol has dissipated from the pan. Now when it is a substance of a lower alcohol content, well that is a little harder to see. But normally when you let it reduce about a minute or two, the alcohol is gone. I hope this helps you.... If you have more questions feel free to look me up.....

I disagree with the comments that the alcohol will never completely burn off or that there will always be a residual amount.

Water boils at 212 degrees Fahrenheit. If you bring a pan of water to 212 and let it boil long enough, the water will COMPLETELY boil away, and then the pan will start burning.

If you bring a mixture of water and alcohol to 172 degrees Fahrenheit (the boiling point of alcohol) and let the alcohol "boil" long enough, the alcohol will completely boil away, just as water does at its boiling point.

So...Mr. Danger is incorrect...and Mormons are safe.

I don't know the specific temperature, but when things start to boil the alcohol is evaporated.

I have no facts

it starts when poured out of a sealed bottle at room temperature

this is obvious with everclear and faster when cooked (flambe) just less than a minuet
