There are two ways to go about this recipe. The first is you can boil all the gnocchi and fry in several batches, reserve, and then toss in the sauce once it's done. The second way is to work the gnocchi in batches and add the sauce to the pan in smaller portions to finish. Since I have a large family who hate to wait for their supper, I tend to do all the gnocchi separately, and then toss them with the finished sauce at the end.
