How Do You Thicken Roast Gravy?
To thicken roast gravy, you can use a combination of cornstarch and cold water or flour and butter. For cornstarch, mix one tablespoon of cornstarch with one tablespoon of cold water until it forms a paste. Then gradually pour it into the simmering gravy while whisking continuously until it thickens to your desired consistency. For flour and butter, make a roux by melting one tablespoon of butter in a saucepan and gradually whisking in one tablespoon of flour until it forms a paste. Cook it for a minute or two before gradually adding it to the simmering gravy while whisking continuously until it thickens to your desired consistency.
