It took me a few iterations to make it work. The recipe I started from was mostly just pasta in ricotta, with chopped walnuts and pepper. I also once tried blending nuts with the ricotta but eventually concluded that the ricotta flavor and creamy texture both gets lost when used as a sauce, while the walnuts gets lost if mixed with the ricotta, so I ended up sort of switching their roles.
