While your gnocchi is cooking get your sauce ready. Use a medium sauce pan and heat on a medium to medium high temperature. Add 4 Tablespoons butter, vegetable oil, and 4 sage leaves. Adding the vegetable oil prevents milk solids from burning. You are looking to achieve a toasted brown color, this is the milk solids cooking. Lower the flame and add the cooked gnocchi and a couple of tablespoons of cooked gnocchi water to create a creamy sauce.
