When you cook with wine or cognac, for example, most of the alcohol simply evaporates when heated and exposed to air. What's left is primarily sugar, plus flavors from the grapes/grain in the liquid.
18-20% alcohol
I can tell you right now that if there is much alcohol in it that it's not a lot at all. It just depends on which brand of cooking spray you use, but 99% of cooking sprays don't have alcohol in them. Hope that helped!
As long as there is cooking time after it is added. It doesn't take very long for the alcohol to cook off.
Yes, igniting brandy can help burn off some of the alcohol, but it's not a foolproof method. When heated, the alcohol evaporates, and igniting it can burn off a portion of the alcohol content, but not all of it. The duration of the flame and the temperature will affect how much alcohol remains. If you're looking to reduce the alcohol content significantly, cooking it for a longer period is more effective than simply igniting it.
LPG means Liquid propane gas. This is simply a combustible heat source that can be used for cooking.
Cooking oil is generally less dense than rubbing alcohol. Most cooking oils have a density of about 0.91 to 0.93 g/cm³, while rubbing alcohol (isopropyl alcohol) typically has a density of around 0.79 g/cm³. This means that rubbing alcohol is less dense than cooking oil, allowing the oil to float on top if the two are mixed.
hahahahaha
yes
No, it is not safe to microwave alcohol for cooking or heating purposes as it can create a fire hazard due to its low flash point.
Physical size, gender, amount of alcohol consumed, time period over which alcohol is consumed, contents of stomach, etc.
Many thermometers contain alcohol because it is less toxic than mercury. In addition to this, the contents of an alcohol thermometer can evaporate away quickly.
Yes. You'll know the alcohol is boiling off because you can smell it.
