Instructions

1. Mix the jelly with water in a jar according to packaging instructions (use slightly less water), and put it in refrigerator for about one hour until set.
2. Wash the oranges, cut off their tops (about a quarter), then carefully scrape out the orange flesh with a spoon.
3. Draw a scary face on the orange skin and, using a craft knife, cut the shapes out.
4. When the jelly is fully set take it out of the fridge and mash it up with a fork. Fill the oranges with the jelly and put the top back on.
