Yes, traditionally can be used (as can wine, depending on the recipe) to deglaze a pan (that is, dissolve stuck-on browned bits after panfrying meat). It's then reduced, and starch may be added to thicken it, and often times butter, herbs, or garlic or onions for additional flavor. It's a simple, common technique to make things like steak sauce.
Well, -going out on a limb, as I don't know the exact constitution of either one, I would say it sounds reasonable and certainly worth trying.
Chicken broth
Chicken broth is needed in the Thanksgiving gravy.
Physically yes. There isn't very much of a chemical difference between the two (i.e. your dish won't explode if you substitute beef for chicken). However, your dish will taste very different, as beef broth is generally heavier and saltier tasting.
In lieu of turkey drippings, try chicken broth. I do this every Thanksgiving or any time I wish to make giblet gravy. Canned chicken broth is okay, but boiling a chicken with some onions and salt is better. Here's how I do it: Boil a few chicken thighs for about an hour. Meanwhile, boil an egg. Melt about half a stick of butter in a saucepan. Add about 1/3 cup of flour to the butter and mix well. Slowly add the chicken broth, stirring constantly. I usually add about 1/4 cup at a time. Continue adding broth until your gravy is the right consistency. Grate the boiled egg into the gravy. Take one of the chicken thighs and chop up the meat finely. Use this instead of giblets (tastes better anyway!)
nope!
To make the white color chicken gravy, kindly use gravy salt coloring.
It is called 'au jous'.
You can ask for Chicken tikka Masala (dry / gravy) the gravy will be a curry.
Although gravy can contain bits of or broth from chicken, turkey, beef, or other meat, leading to thinking that gravy belongs solely in the meat/protein food group, it likely belongs more in the bread/starch/carbohydrate group due to flour that is used to thicken the broth to make gravy. Some 'foods' that we eat do not belong to any specific category. For example: jello, candy and gravy do not belong to any one category. The gravy my family fixes includes flour, milk and oil. So, that's part of three different food categories. Grain, dairy and fats/oil.
yes you can never have to much gravy
It is a liquid food that can be used for a soup, gravy or sauce
Chicken of today does not live long enough to provide enough fat for a flavorful gravy. So they use beef or turkey.
