Does "Khamar" mean you can't have Ice Cream?

[Lobotomize94]

A lot of ice cream uses a little bit of vanilla extract which has 35% alcohol in it.

Does "khamar" mean alcohol or does it mean a substance that intoxicates you? If you drink regular drinking water for example, there will be trace amounts of alcohol in the water (there may even be a molecule or two of Lead for example--not significant, but it's there)--so how are you supposed to avoid alcohol?

Maybe the issue isn't "alcohol" but substances that intoxicate? So drinking water, while it has alcohol is not significant enough to intoxicate and so is okay to eat. Likewise, Ice cream which uses vanilla extract is not enough to intoxicate and so is okay to eat?
