Cook sausage breaking into small crumbles. You don't want large chunks of sausage for this recipe. If you'll freeze the butter for at least 30 minutes, then take it out and grate it on the large-hole side of a cheese grate, it will be much easier to work into the flour. You can use this technique anytime a recipe calls for cutting butter into the flour. If your butter is not frozen, use the traditional method of cutting butter into the flour.
