Step 1

In a large heavy based pot bring 3 litres of water to the rolling boil, add salt at point of boiling a good three to four large pinches. Add the pasta and cook in accordance to the packet. Drain and reserve a large mug of the pasta cooking water. 

Step 2

Meanwhile heat in a large frying pan a couple tbsp of the butter add three quarters of the pepper and cook, ensuring to get all the pepper covered in the butter and toasting it till it is fragrant generally about 1-2 min. 

Step 3

Add halt the pasta water to the pan and simmer, toss in the pasta and the remaining butter, reduce to a low heat and add in Grana Padano, stir and toss to ensure you cover the pasta with the sauce. You can add more pasta water if a little dry.  Now turn off the heat add the Pecorino and transfer to warm bowls, season with more black pepper and enjoy.  So very simple but makes a statement on the testbeds and memory.
