Question

does one add milk, cream, or dry creamer before pouring coffee?

Answer 1

Personal preference...it helps to keep the cup or mug from staining, but that's about it.

Answer 2

Adding milk or cream before the coffee prevents curdling (seen as lighter swirls). I doubt this is necessary for "kreemer" or other petroleum products.
