Place the strawberries into a food processor, and pulse until completely smooth. Pour the strawberry puree through a fine mesh sieve to remove any seeds or solids; set aside.
In a small microwave-safe bowl, combine the gelatin and water; set aside.
In a stand mixer fitted with the whisk attachment, beat the cream cheese, sugar, lemon juice, vanilla, and salt together until combined. Add the heavy cream, and continue beating until mixture is light and fluffy. Start on the low setting, then as mixture thickens, turn mixer up to high.
Once gelatin has absorbed all of the water, pour 4 Tablespoons of the strawberry puree into the gelatin mixture. Heat in the microwave for 15-20 seconds, then stir until smooth and completely liquified. Pour mixture into the remaining puree, stirring to combine.
Pour half of the strawberry mixture into the whipped cream cheese mixture, and beat until combined. Add the remaining strawberry mixture, and use a silicone spatula to fold everything together.
