Gravy is too salty

No, but I have some whole milk, do you think that would work as a sub for cream?

Or sour cream?

Yes, definitely. I would just stretch the gravy with milk and then you'll probably need to thicken it with either a couple tablespoons of flour and water shaken in a jar (pour it in slowly while whisking like crazy), or Wondra flour sprinkled in if you have it.

Thank you soooo much!

Good luck! Let me know how it goes.
