Use to make RTR hard or as edible glue.
add 1/2 teaspoon to about a golf ball size amount of RTR. Knead through and model and shape fondant. Use supports to dry in shape.
Add 1 tspn of cellogen to 50ml of hot water. Stir and shake. Leave to sit overnight. It will start off looking like sago and then clear up.
If you want your glue thicker, add more powder. If you want it thinner, add more warm water slowly.
