Instructions

1. Bring a large pot of salted water to boil.
2. Put 3/4 of the butter into a pan large enough to hold the cooked and drained pasta and melt over medium heat. Add half of the anchovies and stir till they are dissolved.
3. Once the water has been brought to a boil, add the pasta and cook until al dente. If it is fresh pasta it will cook very quickly, so keep your eye on it
4. Drain the pasta, reserving a cup of the pasta cooking water.
5. Over medium heat, add the drained pasta to the pan with the butter and toss well to coat.
6. Add about a quarter of a cup of the cooking water, stirring well.
7. Turn off the heat and add the rest of the butter, and a bit more of the pasta water, stirring to amalgamate.
8. Add the rest of the anchovies, toss, and serve immediately.
