Shaving pecorino and then just throwing it in will make the sheets stick together, so spread it out. You could also grate half of it. Pulse pesto only roughly in your blender, push, stop, push, stop and so on. 50g of basil leaves is a lot; cheat by adding stems if you are not afraid of the basil pesto police.
Lots of cheese, salted pistachios and anchovies mean you need to salt your pasta water less. Great for a date night.

Notes - 150g of pistachios for 75g kernel - toast pistachios before chopping - shaved pecorino sheets will stick together - less salt into water than usual
