I made these crackers by adding multigrain mix (linseed, oats, rye, cornmeal etc.) that I bought from a store selling breadmaking supplies. This made a multigrain cracker, which I felt was more wholesome, but you can make it without this.
Ingredients:
1 cup wholemeal SR flour
Pinch Salt
3 tb butter
1/3 cup grated cheese
1 tb dried chives (or other herbs)
¼ cup water
Optional:
¼ cup multigrain mixture (or linseeds, bran flakes etc.)
dash of water extra
Method:
1). Put the flour and salt into a large bowl, and rub in the butter.
2). Mix in the cheese, chives and any additional grains.
3). Make a well in the centre, and add in the water. If you have added extra grains, you may need to add a little more water to make the mixture come together into a dough-like consistency (it should be fairly dry not sticky).
4). Knead until mixture has come together and is smooth.
5). Turn out onto a floured surface, and roll out as thin as you can, to about 2-3mm thick. Use cookie cutters (or cut squares with a knife) to cut shapes out and lay them on a greased or lined baking tray.
6). Brush the tops with milk, and bake in a preheated oven at 200ºC for 10 minutes, or until they are golden brown (mine in the image above were probably a touch overcooked).
Allow to cool completely before putting in an airtight container.

Super yummy
and not that naughty either
