These crackers can be Gluten Free, Nut Free & Egg Free. If making them for someone with an allergy make sure that you don't "cross-contaminate" your recipe with other ingredients, all utensils need to be thoroughly cleaned away from allergy specific ingredients, and make sure that the individual ingredients you choose are free from allergy items i.e. check the ingredients panel they cannot contain traces of.

Steps:

1. Preheat the oven to 160°C. 
2. Combine all the ingredients and leave the mixture to stand in the bowl until it is thick and pliable (about 10 mins). 
3. Spread the mixture out as thinly as possible on baking paper on 2 baking trays, this may be easier using the back of a metal spoon to smooth the mixture and spread it as thinly as you can, the thinner you can make it the crispier the crackers will be, the mix should have no holes in it. 
4. Bake 60 - 75 minutes till crispy, rotating the tray every 15-20 minutes to cook the mixture evenly.  
5. Remove tray from the oven and leave to cool.
6. Once cooled, break crackers into pieces and store them in an airtight container.
