Not in 7 years, anyway! It does tend to concentrate a bit--you may need to use slightly less.
It's most likely the high alchohol content that gives you the idea of it tasting bad.
yes it can I had a bad toothache and i took a q-tip and put it in the lemon extract and it really works.
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.
Is it bad for you to reuse a plastic bottle
Yes, vanilla wafers are not good to feed your dog as they have sugar in them.
They're aren't necessarily healthy or unhealthy, but they're a great substitute for vanilla extract. (If you can afford it!) I would recommend buying them @ Costco for the best value. You can also make vanilla flavored sugar by putting a used vanilla pod in a container of regular granulated sugar. This gives the sugar an amazing aroma and makes it so the outside part of the pod doesn't get wasted.
No
It is neither good nor bad. It is used by the teaspoonful.
I have no idea - there's no medical reason for this. I would guess someone somewhere claimed this was a good "natural" or "herbal" remedy for something, although I will point out most vanilla extract is artificial and has no real vanilla in it. This is also a pretty bad idea - the risk of inhaling the liquid and causing inflammation in the nose is pretty high. Also, dogs have very sensitive senses of smell - this is the equivalent of putting an air horn to your ear and hitting the button. This would cause a great deal of distress and irritation to your dog, and there's no reason to be mean to your dog like that. Additional information: It is not put on the nose, but some dog breeders have used a small dab of vanilla extract on a male dog's collar to keep him from getting too whiny and anxious from the scent of a nearby female who is in heat. They say it partially masks the scent of the female.
Vanilla Wafers do not give dogs worms but the sugar content, if given in excess, is very bad for a dog's teeth.
Even though vanilla taste bad by itself, it can taste different when you add ingredients because vanilla is such a thin (not as powerful) formula it is easy for other ingredients to sink into it. For Example: If you add sugar to vanilla it will change its flavor because the sugar has made it more sweet. The same thing will happen with brown sugar, too. If you add a wiped egg yolk with vanilla it will also change its taste because an egg yolk has a different flavor. The flavors will combine to make a new one. Vanilla might have a strong taste but it is not a strong ingredient.
