- Grab an apple.
- Cut out a grin, with a sharp knife.
- Push slivered almonds into top and/or bottom of apple, to represent teeth.
- If it will be a while before serving, paint orange or lemon juice over the apple flesh, to stop it going brown.
- Tip: the bigger the mouth, the easier to push the teeth in.
- You can go for the buck toothed look, with wide slivers of almonds.
- Make lots of smaller mouths, by cutting apple into quarters, and turning each quarter into a gruesome grin.
