Blend the watermelon in a blender until smooth.
Strain the blended watermelon through a fine mesh sieve. For a really clear liquid place a cheese cloth or tea towel in the sieve so that all the pulp is captured which you can either discard or use in another recipe such as a smoothie or jelly - you should have about 2 cups of juice.
There may be some white foam at the top of the watermelon juice, which you can remove so that you have a nice clear liquid.
Place half the watermelon juice in a bowl and the other half in a pan.
Add the Grass Fed Gelatin powder to the watermelon juice in the bowl by sprinkling it over the surface. Let it sit for a few minutes so that it dissolves into the juice. It will become jelly like.
Gently heat the other half of the watermelon juice in the saucepan just to warm it.
Add the gelatin & juice mixture from the bowl to the juice in the saucepan.
Whisk or stir to combine until the liquid is smooth.
Add the honey and lemon juice (leave this out if you prefer the gummies to be more sweet) my kids love sour gummies so we keep the lemon juice and sometimes use lime juice for extra tang) and whisk until dissolved and combined.
Pour the gelatin mixture into your favourite jelly or chocolate mould and chill until set, about 2 hours.
When they are ready remove the gelatin from the mould and store either at room temperature or in the fridge.
