In my pesto I use walnuts instead of pine nuts because it has a stronger taste. I have also done this with parsley instead of basil.
a bunch of basil leaves
2-3 cloves of garlic
ca 125 ml (½ cup) walnuts
ca 125 ml (½ cup) fresh grated parmesan
salt and pepper
Mix all the ingredients in a blender, starting with the basil leaves, garlic and some olive oil. Add the walnuts and for last the cheese. Season with salt and pepper. If necessary add more olive oil.
Serve with fresh pasta or egg pasta and a simple tomato salad. Great with red wine or a bubbly prosecco.
