Of course. Just remember that a little goes a long way. Also try adding some during your boil to give a hint of the spice in the background flavor profile.
What do you mean what do they add to it? It's beer. Why would they add something to it.
Yes. I like to marinate my lamb in oriental spices then add a lttle honey glaze when its done.
By adding a little bit of curd.
Different spices add different taste to what you are cooking
I done this last year just add green food clouring it really works
Just add beer to your frying batter
They are used to add more flavor, some add color as well.
I am not aware of any beer made with meat or meat by-products. The entire idea sort of makes my stomach turn. I think most, if not all, beer is made from all vegitable (non-meat) materials: water, hops, barley, malt, and yeast (which is kind of alive, but not really in the "moo cow" way). Then you can add a whole host of other ingredients like spices, fruits, and so forth to broaden the flavor. However, meatloaf and sausages are never used in the fermenting process as far as I know. You can try it if you wish, but... please don't invite me to the sampling party. I think beer is a pretty safe vegan option... unless the whole yeast/bacteria thing qualifies as "animal."
To add flavor to something means to add spices to a food dish.
Add spices, herbs, salt, garlic
The ancient Europeans used spices to preserve food and add flavor to the bland foods.
There's no great mystery why people add spices and herbs to things. They taste good! It's as simple as that.
