Start by preparing your unflavored gelatin. Mix the gelatin with water in a microwave safe cup or bowl. Microwave for 25 seconds. Give it a light stir once you remove it from the microwave.
Make sure your frozen passion fruit pulp has been defrosted and is in liquid form. This can be done by simply running cold water over it for about 5 minutes.
In a blender, combine the passion fruit pulp, sweetened condensed milk, whole milk, table cream and gelatin. Blend for approximately 2-3 minutes or until all the ingredients are well combined.
Transfer your passion fruit mousse to an air tight container. Top off your passion fruit mousse with the cooled passion fruit simple syrup topping.
Refrigerate for 6-8 hours for optimal results and texture.
Garnish with mint leaves or fruits if you desire. Serve and enjoy!
