In a small ceramic dish, combine the powdered gelatin with 1/4 cup of water. Stir, then leave to swell for 5 minutes.
Simmer the raspberries and half a cup of water in a small saucepan for 4 minutes, or until soft and falling apart.
Remove the berries from the heat.
Removing the seeds from the raspberries is an optional step, but the texture is smoother without seeds. Place a wire sieve over a glass jug to strain the raspberry sauce. Use the back of a spoon to push all the fruit pulp through a sieve, into the jug - discard the seeds.
Return the raspberry sauce to the saucepan, and add the gelatin.
Place the saucepan on the stovetop and heat gently, while stirring with a spoon. The gelatin will dissolve immediately and only needs to be warmed to 95-104 F to activate. Do not boil the gelatin and raspberry mixture.
Remove from the heat and stir in the honey.
Set aside and allow to cool-down before pouring onto the set, smoothie layer.
When the underneath of the saucepan is 'luke-warm' to touch, pour the raspberry sauce onto the smoothie layer.
Transfer to the fridge to set firm.
Slice the gummy into bite sized squares.
Store in a sealed container in the fridge for up to 1 week.
