Silky Spaghetti al Limone

Method

Cook with patience

1. 1

   Bring a wide pan of well-salted water to the boil. Cook spaghetti until just shy of al dente.

2. 2

   Melt butter gently in a large skillet. Add the finely grated lemon zest and a generous turn of black pepper.

3. 3

   Lift pasta into the skillet with a splash of cooking water. Toss until the butter begins to coat every strand.

4. 4

   Take off the heat, add finely grated Parmigiano and toss quickly. Loosen with more pasta water until glossy. Finish with lemon juice.
