Preparation method

1. Combine jelly, gelatine and boiling water, and stir to dissolve.
2. Meanwhile, arrange all the straws in an upright container with a flat surface (they must fit very snugly).
3. Carefully pour jelly into straws, and pop into the fridge to set.
4. When jelly is set, squeeze the ‘worms’ out of the straws with your fingers. If the jelly is stuck to the straw, use a hot damp cloth or a hot rolling pin to ease it out.
5. Blitz the Oreos in a food processor to create ‘dirt’.
6. Sprinkle the Oreo dirt onto a plate or into a small bucket bowl, and arrange the jelly worms in the dirt.
