My husband is requesting biscuits and chipped beef gravy for his birthday dinner. I have never made biscuits and gravy before. I'm pretty confident on the biscuits but I haven't found a recipe for chipped beef gravy. I was thinking of following wssmom's buttermilk biscuits with sausage gravy recipe https://food52.com/recipes..., but I'm not sure if I can just substitute chipped beef for the sausage. And how much?
