To make your own jelly beans you need:
1 packet 500g or 4 cups and 3 table spoons cornflour
A baking tray
100g or 1/2 cup sugar
40 millilitres water
20g corn syrup
1 table spoon cornflour
For the different colours: food colour and different flavours
[...]
Mix together the sugar and cornflour until it's smooth, then add the water and syrup. Heat everything to 120 degrees Celsius using a thermometer to check the temperature.
Then pour the syrup into the molds and leave it to cool for at least a couple of hours.
Sift off the cornflour. Then coat the beans with the colours and flavours you like.
