Preheat oven to 150 degrees fan forced
Place one rack on lowest shelf, and the other rack second from the top so that you can bake two trays at a time
Get two baking trays ready, and also cooling trays if you have them ... you will need two but if you don't have them the crackers can cool on a tray as long as they are in a single line
Cut your loaf in half lengthways down the middle
Lay each half on its side and cut into thin slices to suit
Place the slices onto the baking trays facing the same direction
Bake for 10 minutes, remove from oven and turn the slices over, return the trays to the oven
Bake for 8 minutes, remove from oven and feel the slices ... if they are firm remove to a cooling rack to cool
Leave the rest on a single baking tray but ensure they are turned over again
Bake for 3 minutes, remove from oven and feel the slices again removing the ones that are now firm but leave the others there ... you should only have a few left now ... these will be the ones that may have been slightly thicker than the rest ... turn them over again
Bake for 3 minutes where they should be firm by now, but if not repeat the process until they are
Allow to cool completely before storing in a sealed container
Crackers will keep for up to two months, but can be refreshed in the oven for a few minutes if you feel they need it
