how much alcohol is cooked away in preparing agar agar? [duplicate]

I make vegan jello by dissolving agar agar in boiling water. Sometimes I add liqueur (e.g. Grand Marnier) for a little flavoring and sweetness, in which case I would add about 0.5 cup of liqueur to 5.5 cups of water and bring it to a boil for about 15 minutes.

Is there an approx. concentration of residual alcohol remaining in the agar agar jello (called "kanten" in Japanese)? As an example, the liqueur used is 40% alcohol.

Best Answer

There is a misconception that alcohol will easily burn off when used in cooking, and since pure alcohol has a lower boiling point than water, if you mix them, it is thought, the alcohol will burn off first.

The reality is that when mixed together the situation gets more complicated and the new boiling point of this solution is neither that of pure alcohol (173°F/78°C) nor water (212°F/100°C) and will fall between depending on the ratio of the mixture (keeping in mind that you started with water in your alcohol).

So if you want to cook with alcohol and burn more of it off it's best to do so before adding water. In your case you may want to cook down the liqueur first to remove more of the alcohol. If you combine them as you have been, you can assume that you'll burn off a similar ratio of water and alcohol from the solution.

Is agar agar heat resistant?

Agar may be dispersed in either hot or cold medium. Hydration (dissolution) occurs at temperatures above 90\xb0C; heating the solution to a boil is necessary for gelling. Setting occurs at 35-45\xb0C, and onset is rapid (within minutes). Melting of agar gels occurs at 80-90\xb0C.
