The word “moka” should be used to refer to Arabian coffee. In fact, only the coffee beans picked on the borders of the Red Sea have the right to be called “moka”, which derives from the name of the Yemenite port from which they were traditionally exported. In this case, an excellent instant coffee is recommended for use.
In a wide-bottomed pan, brown the finely chopped garlic and onion in butter. Add the bacon cut into julienne strips with the walnuts and sprinkle with instant coffee. Lower the flame and slowly cream the mascarpone cheese. Cook the pasta in plenty of boiling, salted water following the instructions given on the packet and drain when it is “al dente”. Sauté in the pan and season with salt and pepper.
