This is for all, like myself, who don't use any kind of alcohol, but want the flavor in some of our recipes. And, NO, it doesn't always cook off; only if you flame it. And that only takes it down to 75%. Baking or simmering 15 min takes it down to 40%; baking or simmering 2 hours 30 minutes takes it down to 5%. This is according to the US Dept of Agriculture. Cooking times are approximate, according to recipe.
