Pre heat the oven per package instruction on your can of biscuits and bake accordingly. Proceed to make the gravy while the biscuits cook
Brown the sausage and break it into small bite size pieces
Once the sausage renders fat, put it in a colander and collect the fat to make the gravy
Return the fat to the pan, add the flour and stir until it forms a paste. I like to use a wooden spoon or silicone spatula for this
Add a splash of milk and make sure to breakdown any lumps to get a smooth thick consistency
Add the rest of the milk and bring to a gentle simmer
add the sausage back in
add salt and pepper to taste and keep on low until ready to serve
Serve over a split open biscuit. Add some butter if you want to
