Kids love these and it is fun for them to make them. They take no time at all and look great too. They have tonnes of sugar though, so do not let the kids make them too often.
You need:
23 gr flavoured jelly (we used raspberry)
25 gr neutral jelly
150 ml fruit juice (we used apple juice)
75 gr sugar
Put all the ingredients in a small pan and heat the mixture for 10 minutes, removing it from time to time with a spoon. Do not let it boil. While the mixture is getting hot, oil well silicon moulds with sunflower oil (we used moulds to make ice cubes). You really need to oil the moulds well or the gums will not come out smooth. Pour the mixture over the oiled moulds, wait for 3-4 hours ( no need to put this in the fridge) and unmould. You can roll the gums in caster sugar but they are very nice on their own too.
