In a large bowl, mix the flour, beer, and salt thoroughly, then knead the dough until smooth.
Lightly flour your baking tray
Divide the dough into the desired number of rolls, breaking off pieces and keeping them covered while shaping.
To shape: tuck the edges under to form flat, round rolls, coat in flour, press down gently, and rotate to even out the shape.
Arrange the rolls on the prepared baking tray.
Place the tray in the oven at a very low temperature (it should not be hot) for 30 minutes to an hour to allow the dough to rest.
Remove the rolls from the oven and barbeque them over hot coals, turning frequently for an even, golden crust. They will be light in weight, then you know they are cookes.
