I think I am going to splurge for a 1/2 cup or so of mashed potatoes
next Thursday and would like to have gravy too. I suppose that, with
the large jolt of carbs from the previously total abstinence from
potatoes, what could a few more from gravy hurt.....supposedly 45
carbs or so worth, but......

an entire cup of canned turkey gravy only has 12 grams of carbs.

i don't think you need to worry about it.
