In large mixing bowl, beat ricotta cheese, cream cheese, sugar, honey, applesauce, and flour with an electric mixer on medium to high speed until smooth. Add egg yolks all at once. Beat on low speed just until combined. In a clean large mixing bowl with clean beaters, beat egg whites with an electric mixer on medium to high speed until stiff peaks form (tips stand straight). Fold about one-fourth of the egg whites into the ricotta mixture. Fold in remaining egg whites.
