Bloom the gelatine & packet of jelly by adding to a bowl and adding 1 tsp room temp water- leave for 5 minutes to let the gelatine activate
add 1/2 cup boiling water- a little bit at a time and stir well. if there are any clumps continue to stir until they are gone
If the clumps are too hard to mix, add the mixture in the microwave for 30 seconds and stir well
Add 1/2 tsp -1 tsp citric acid (depending how sour you like it) and stir well
Add mixture to your moulds of choice or if you do not have any, add the mixture to a rectangular Tupperware of choice (lay some baking paper down first so they don’t stick)
refrigerate for minimum 1 hour
pop out of the moulds or cut into jelly snakes if using the Tupperware
