Roast the walnuts a little, then let them cool. Puree all ingredients to a fine mass. Season the pesto again and season with salt and pepper if necessary.
Tips for serving:
Boil 400 - 500g pasta. Roast 50 g pine nuts in a pan. Mix the dripping wet pasta with the pesto, add a little pasta water, vegetable broth or cream if necessary. Fold in the pine nuts and serve.
The pesto also tastes great as a spread on fresh bread or together with pasta as a pasta salad for grilled foods. Then first add only 2/3 of the pesto to the pasta and let it steep for at least 30 minutes. Gladly also in the refrigerator. Finally, heat the rest of the pesto in a cup in the microwave, stretch it a little if necessary and add to the salad with the pine nuts and - depending on your taste - halved cocktail tomatoes. This way the salad doesn`t get dry.
