Made gnocci the other night and thought of this post - I was looking for an interesting sauce that had neither tomatoes, cream nor fresh sage as my pantry was out of these. I found a vegan recipe which I adapted as follows - the chunky bits of nuts make a really nice contrast with the soft gnocchi:
3 large cloves of garlic, peeled and crushed
1 tbsp butter, 2 tbsp EVOO
chili oil to taste
Walnuts and Pignoli (to make 3/4 cup chopped)
Grated rind and juice of 2 large lemons
Salt and freshly ground black pepper
Water from the pasta you're cooking to put this on
1/4 cup of chopped fresh parsley - a bit reserved for garnish
Cook the garlic in olive oil, butter and chilli oil for a few seconds.
Toast walnuts and pine nuts in a skillet until fragrant, then toss them in the food processor or blender until you have a variety of textures: fine bits, chunky bits, etc. You will need 3/4 cup chopped nuts, about equal parts of each type. Stir into the oil with lemon rind and cook for a few more seconds.
Add the lemon juice, salt, pepper and parsley. Add pasta water until the sauce is the desired consistency. Keep the sauce warm. Serve over gnocchi and garnish with remaining parsley.
