To make beef gravy take two beef bouillon cubes and one cup of water and bring to a boil. While waiting for the water to boil get one cup of cold water and mix about a 1/2 cup of flour. Mix the flour and water combination with a whisk until smooth. When your water has come to a full boil slowly start adding your water flour mixture to your hot water whisking it as you’re adding the mixture. Continue to add the mixture and heat until desired consistency.
