Preheat oven to 180°C.
Combine all dry ingredients in a mixing bowl.
Gradually add water, stirring to combine mixture. You will end up with a thick 'dough'.
Spread mixture out on to a lined baking tray. Using fingertips or back of a spoon, press and smooth the mixture out so it is no more than 5mm thick.
Using a sharp knife, deeply score/cut your dough into desired cracker shapes.
Bake in oven for approximately 30-35 minutes (check to make sure they are not burning).
Remove from oven and allow to cool completely, then break into crackers.
Store in an airtight container for up to 2 weeks.
