In a saucepan cook the strawberries and 1 cup sugar over medium-low heat. If you are using fresh strawberries you may need to add 2 tablespoons of water. Cook until the fruit is softened. Frozen and VERY ripe fruit will cook faster.
Use a regular or immersion hand blender to puree the fruit. Strain the seeds and return to the pot. Using a chinoise strainer will make the job go much faster.
In a small bowl, pour the 3 packets of gelatin over 1/2 cup of water, making sure no dry powder remains. Let the gelatin sit until it "blooms" and absorbs all the water.
Heat the strained puree to a simmer, turn off the heat and add the bloomed gelatin. Stir until the gelatin is melted and evenly distributed in the puree.
Choose a mold that fits at least 5 cups. I used a silicone mold, such as the Lekue Imperial Monarch Mold.
Fill the mold with 3/4 of the puree. Set the mold in the refrigerator for 30 minutes or until a skin is formed on the top.
Pour half the remaining puree into a bowl. Whip the heavy cream with 2 tablespoons sugar and add it to the puree in the bowl.
Gently fold the cream into the puree.
Add the cream/puree mixture to the mold, refrigerate for about 15 minutes, or until it has set slightly. Add the remaining strawberry puree to the top. Set in the refrigerator for about 3 hours or until well set.
To un-mold the jello: fill a large vessel with hot water.
Dip the jello into the hot water, being careful not to get water over the lip of the mold. You may need to use a knife to carefully separate the edge of the mold from the jello. Let the mold sit in the water for 15 to 30 seconds. Set the jello on a platter.
Refrigerate until ready to serve.
Use a thin bladed knife dipped in hot water to cut the jello.
