Place Parmigiano-Reggiano, ricotta and egg in bowl section of food processor. Mix until smooth. Put 3/4 cup of flour into a separate bowl and fold in cheese mixture. Knead all together until fully incorporated, being sure not to over-knead. If mixture becomes gummy, you have gone too far.
Liberally dust the table top and your hands using 1/2 cup flour. Divide the gnocchi mixture into 8 equal pieces. Using your hands, roll each piece into a cylinder 1/2 inch in diameter, dusting with additional flour as needed.
Cut cylinders into 1 inch long pieces and place on a parchment-lined sheet pan that has been dusted with flour. Refrigerate for 1 hour.
Fill a large bowl with ice and water. Use this as a bath to shock the gnocchi after cooking.
Bring 1 gallon of salted water to a boil. Add half the gnocchi, cover pot, and boil until gnocchi rise to the top (approximately 3 minutes). Remove immediately with a slotted spoon and place in the ice water bath. Repeat process with remaining gnocchi.
When gnocchi have cooled, remove from water and place in non-reactive pan. Coat with 2 tablespoons of olive oil and refrigerate.
To serve, reheat gnocchi in a large pot of boiling water for 1 minute and serve with morel or your favorite sauce and garnish.
Place butter and shallot in 1-quart sauce pot over medium heat. Cook until translucent. Add morels and pinch of salt. Cook for 3 minutes stirring occasionally. Add white wine and reduce by two thirds. Add chicken stock reducing again by two thirds. Add heavy cream, turn down heat and simmer for 20 minutes or until sauce coats the back of a spoon. Season with salt and pepper.;
