First peel the oranges for 100 grams of peels. Only peel the skin and not the white part. Now blanch the peels 4 times. Every time you need to take new water. This will remove the bitter flavor. Once that’s done transfer the peels into a blender and also add the orange juice, the sugar and the salt. Now blend this till smooth and then pour it into a saucepan. Also add the agar powder and while stirring bring it to a boil for 1 minute. Then pour it into a bowl and let it cool down in your fridge. Once it’s set transfer it into a blender and blend it into a delicious and smooth cream. Now transfer it into a piping bottle and keep it in your fridge for later.
