1Preheat the oven to 180°C (360° F) and line a tray with non-stick baking paper.
2In a large bowl, combine all the seeds and salt with your choice of seasoning (choose between "Cheese" + Onion, Italian herb or Spicy). Add the water and stir until well-combined. Taste and adjust seasoning if desired. Allow the mixture to sit for 30 minutes until all the water has been absorbed.
3Spread the mixture onto the prepared tray using a large spatula. Ideally it should be no higher than 5mm. Score the mixture by pressing a sharp knife down to create lines. This will make it easier to break into evenly sized crackers after cooking.
4Bake for 30 minutes. Remove from oven and break into individual crackers. This should be fairly simply if the mixture was scored well before cooking. Carefully turn the crackers over and return to the oven for an additional 20 minutes.
5TIP: For extra crunch, allow to cool completely in the oven before eating.
