The color and flavor might be a bit off, but it should work fairly well.
There are several good rated brands of imitation vanilla extract, but some of my favourites are Flurber's Imitation Vanilla Extract, and Hopperstein's Imitation Vanilla Extract.
There is no alcohol in imitation vanilla extract
No. Only "pure" vanilla extract is made with alcohol
I have only used imitation vanilla when making chocolate chip cookies. Yes, and it will make little difference in the final product, since the main flavor of chocolate chip cookies comes from a combination of ingredients, including brown sugar, butter and chocolate chips. Using high quality pure vanilla is more important when it's the primary flavoring, like vanilla ice cream or custard.
"Pure" vanilla extract generally contains 35-40% alcohol... "Imitation" vanilla does not use alcohol as an ingredient
vanilla extract with a little tiny bit of lemon eetract
real vanilla extract would be even better
You don't necessarily NEED vanilla extract in cookies, but it vanilla extract does add flavor to the recipe. I have accidentally left it out of a cookie recipe before, and you can definitely tell the difference. Without the vanilla extract, the cookies taste very bland.
Vanilla extract can be replaced by almond, anise, mint, lemon or any other flavoring of your choosing. You also can leave out the flavoring or extract entirely. In that case, the cookies will be butter-flavored.
You can but your finished recipe will taste of lemon not vanilla.
It is safe to say that 1 drop of the double strength is equivalent to 2 drops of regular vanilla extract. The best tasting vanilla comes from the best extract or the beans, though.
"Pure" vanilla extract is, in effect, a liqueur and should have an indefinite shelf life provided it is stored properly.
