when all the grease is soaked up in the flour, you add a small amount of milk. maybe about 1/2 cup at a time. with your spoon or whisk, whisk the milk around to mix it with the flour lumps. since the heat is up high, the milk will absorb quickly, so keep adding the milk a little at a time while whisking until the milk no longer absorbs in the flour. whisk it together until all the lumps are out. it may be thicker than you want, and it may seem there isnt enough gravy, thats ok.
usually what makes gravy lumpy is the heat is too low, and there was not enough grease. when the lumps are gone, lower heat a little, and add more milk and stir in with gravy until desired consistancy. add salt and pepper to taste.
hope that helps. PM me if you need more help! i LOVE to cook, in fact, i do it for a living!
