For the black pepper, traditionally you should toast black pepper corns on a pan with medium heat until you smell the aroma and then crush them into dust with a mortar. Although, ground pepper out of a pepper mill is completely fine
In a bowl add 3 tbsp of the mixture for every person and add some black pepper. The whole mix makes about 4 portions. Then gradually add some tablespoons of pasta water and mix until the consistency is creamy and smooth. Toss the pasta in the sauce until it is well coated! Enjoy!
