Going Crackers

With the New Year came enforced respite in the form of a raging cold that isn't letting go. It's likely the result of all that frantic activity --- two sets of house guests, holiday meals and several vocal outings, as well as being out in raw weather.
Actually, we've been lucky. Other parts of the country have had major snow and freezing temperatures. My sister in Alaska has snow to the rafters. It was 21 the other morning in Atlanta, where Mom will be going for a couple of weeks in February. Here, we've only had two little dustings of snow. Ski areas on Mt. Hood have slush. We've had several sunny days and average temperatures in the 40's.
Due to a drippy nose, hacking cough and general malaise, I've been staying in and haven't gotten into town to replenish some of my usual pantry staples, including my favorite midnight snack, crackers.
There is a box of whole grain soda crackers on the shelf, but they don't count. I have my Laughing Cow (garlic and herb and blue cheese wedges) plus a chunk of Monterey jack, the other necessary snack components.
It's been years since I attempted homemade crackers. This is not the definitive batch --- there are a few things still to be ironed out --- but I have some satisfactory and reasonable facsimiles.
I started with about 2/3 a cup of cooked 8-grain cereal (Bob's Red Mill). Into the bowl went 3 T. of softened butter, 1/2 cup whole wheat flour, 1/2 cup unbleached flour, 1/4 tsp. soda, 1 tsp. onion powder, 1/2 tsp. garlic powder, 2 T. poppy seeds, 3 T. sesame seeds, 1 tsp. dill seed, 1/2 tsp. celery seed, 1/2 tsp. mustard powder, 1 tsp. Spanish smoked paprika, 1 tsp. sea salt, 1 tsp. Tony's Cajun seasoning, 1/3 cup grated parmesan, and fresh ground pepper. Add just enough buttermilk to barely moisten and gather ingredients into a ball. Cover and put in the refrigerator at least 1/2 hour.
Roll dough into 1" balls and flatten by hand, using more whole wheat flour if it is sticking. Place each flattened ball on parchment paper on a large sheet pan and flatten more. Place in a 300 degree oven at least 30 minutes. Check after 20 minutes, and lower the temperature to 275 if they seem to be browning ahead of schedule. Turn off the oven and let them stay there 10 minutes or so, then remove to a cooking rack. If they are still bendable and not that cracker-like, place in the oven at 275 for another 10-15 minutes. This is a "play it by ear" thing. If you don't flatten them enough, they will be a little doughy. They just need a little less moisture. You can also flatten out one sheet of dough and break it into pieces after it bakes.
I will be perfecting this process, but these are quite tasty.
