While the crust chills, make the filling. Place the cream cheese into a large bowl and stir well until there are no clumps. Add the sour cream, lemon juice, powdered allulose and stir well.
Place 2 tablespoons heavy cream into a small bowl and add the gelatin. Stir well to combine, then heat in 15 second increments until the gelatin has melted. Use a spatula to combine the gelatin mixture into the cream cheese mixture.
Place the rest of the cream into a large bowl and use a hand mixture until stiff peaks form. Stir the whipped cream into the cream cheese mixture. Add the salt and stir well. Taste and adjust sweetness to your liking.
