Place the ricotta in a mixing bowl and whip it with an electric mixer or a whisk until smooth.
Place the heavy cream in a mixing bowl and whip it while adding the sugar a little at a time, until well incorporated.
Fold the whipped cream into the ricotta, then add the following ingredients 1 at a time, mixing carefully: almonds, pistachios, lemon zest, orange zest, and chocolate.
Refrigerate until serving, but don't let it sit for more than 1 hour, or it will lose its fluffiness. Add the strawberries just before serving so that they don't "bleed out" and color the dish.
