Steps to follow:
- In a pot of salted water, cook the spaghetti for the time indicated on the package instructions. Once ready, drain and set aside.
- While pasta is cooking, take the opportunity to peel the pistachios. It won’t take more than 10 minutes, don’t worry.
- In your food processor, add the following ingredients: washed basil leaves, peeled garlic, grated Parmesan cheese, pistachios and olive oil. Blend it well.
- Put the spaghetti on a plate and mix them with the sauce you just prepared.
We do not add salt to pesto sauce because with the flavour of the pistachios and Parmesan cheese it is not necessary, but if you want, you can add a pinch before blend it. If you do not have a scale, to give you an idea, you will need the equivalent to two handfuls of basil leaves.
