What is your opinion on cooking with alcohol, like wine etc. I know most Muslim ruling is NO on the subject. I am personally liberal in general in life and on this subject also. You simply can't get drunk on the food cooked with alcohol.
As discussed in this previous answer, vanilla extract that comes in alcohol is halal since it is not possible to get drunk on it. As for using alcohol in cooking, I believe this is closer to the forbidden side because when used in cooking, the point is to consume the alcohol itself, unlike vanilla extract where the alcohol is merely a carrier for the vanilla, and the Prophet 
says that anything that causes intoxication in large amounts is forbidden in small amounts.
The alcohol in the house may also act as an encouragement for your family members to try it, especially teenagers.
