Mix dry ingredients in a bowl and add the butter and egg and make a dough.
I did find that I had to add a sprinkling of water to get the dough wet enough, but that could be due to the Carbquik.
Take a large cookie sheet and place down a silpad, placing the ball of dough on top.
Cover the dough with a large piece of wax paper
Use a rolling pin to roll the dough about 1/4" thin, or maybe a bit less
Remove the wax paper and score with a pizza cutter (a bit deeply) to the size of cracker you'd like
Sprinkle lightly with a coarse salt and a bit more cheese
Bake at 300F for 40-45 minutes
Remove from oven and let cool COMPLETELY before breaking at score points.
Store uncovered, unrefridgerated.
