In a high powered blender, puree 1 cup of hulled strawberries, sweetener, and a squeeze of lemon juice.
Pour into a mixing bowl and sprinkle gelatin on top of it. Bring water to a boil and then pour over the bowl of pureed strawberries and gelatin. Whisk until there are no clumps and the gelatin is completely dissolved.
Pour into your desired containers and set in the refrigerator to chill (2-4 hours). Your homemade jello cups are ready to tuck into your lunch on the go!
This homemade jello will keep in the fridge for up to a week.
