I don’t know if I am asking the impossible but I’m looking for a potato gnocchi sauce to accompany the gnocchi that does not contain mushrooms or tomato. I have two respective family members that excludes these ingredients and I am sure as shit not going to make 2 different sauces.
Two options are quite common and come to mind:
Blue cheese + heavy cream base sauce. Or a simple sage + butter and pepper.
Use these combinations as your main volume of sauce and add other elements/seasoning however you see fit.
