Kayelle, that recipe is very like the one I use. Here are the differences:
Cook the streaky bacon until crisp, but start it slowly so that it renders its own fat, and save most of the fat to liberally coat the bottom of the skillet. Then de-glaze the skillet with a large splash (1/4 to 1/2 cup) cooking sherry. Pour the fat/sherry mixture over the spaghetti and stir quickly to coat before adding 3 to 4 eggs, depending on the size. Stir vigorously to coat. (I use a wooden fork to do this.)
Then add percorino romano cheese. Top with crumbled bacon and serve.
Sooo good.
