1. Use a Hammer and a Heavy Object:
- Place the hazelnuts on a hard surface, such as a cutting board or a kitchen counter.
- Position a heavy object (like a thick book or a large wooden spoon) on top of the hazelnuts.
- Use a hammer to gently tap the heavy object, cracking the hazelnut shells without damaging the kernels.
2. Use a Rolling Pin:
- Spread the hazelnuts in a single layer on a cutting board or a sturdy surface.
- Roll the rolling pin over the hazelnuts, applying pressure to crack the shells.
- Be careful not to apply too much pressure, as it might crush the kernels.
3. Use a Pliers or Wrench:
- Place a hazelnut between the jaws of a pliers or a wrench, with the shell facing up.
- Gently squeeze the handles of the tool, applying pressure to crack the shell.
- Be careful not to apply too much pressure or you might damage the kernel.
4. Use a Door:
- Place the hazelnuts on the floor near the edge of a closed door.
- With one hand, hold the door closed, while using your other hand to press down on the hazelnuts with your foot, applying pressure to crack the shells.
- Be sure to place something soft (like a towel) underneath the hazelnuts to protect your floor.
5. Use a Jar or Bottle:
- Place a hazelnut inside a sturdy glass jar or bottle, with the shell facing up.
- Hold the jar or bottle firmly with one hand, and use your other hand to tap the bottom of the container against a hard surface, such as a countertop or a table.
- The impact will cause the hazelnut shell to crack.
6. Use a Mortar and Pestle:
- Place the hazelnuts in a mortar and use the pestle to gently crush the shells.
- Be sure to use a light touch, as applying too much pressure might damage the kernels.
Remember, while these methods can be effective in cracking hazelnuts, they might not be as efficient as using a nutcracker. It's important to be patient and careful when cracking hazelnuts without a nutcracker to avoid damaging the kernels.
