I'm sure there are people who know what the flour was like, but I'm not one of them.
What we use today, is properly called,
hard, red wheat. It has more gluten, and even if you use "organic, whole wheat flour" you are going to get a product very unlike what they had then for it will still probably be from hard, red wheat.
The flour of the 18th century, and most of the 19th century, is what we would call today,
whole wheat, pastry flour, and it is made from the
soft, white wheat of yesteryear. It has less gluten and more albumen...
Now back in the 18th century they did try to make various grades of flour, as the wealthy often ate "white" bread, while the poorer sort ate a brown bread, or in some areas "thirds" which was 1/3 wheat flour, 1/3 rye, and 1/3 of another grain (it could be barley, oats, or Indian corn). Oddly enough, the poorer folks eating "thirds" were actually getting much better nutrition than the rich.
SHIP's BISCUIT/HARDTACK
The reason why when many living historians make ship's biscuit or hardtack it is so bloody hard, is they make it out of modern, whole wheat. That extra protein and lack of bran yields a product akin to a cedar, roof shingle. In my opinion it's wrong. I think it's about as close to real hardtack as a Slim Jim is to real jerky...
The
lowest grade of flour was called
ship's stuff, and it wasn't bolted. It was ground, and bagged or barreled. As it was the cheapest flour, ship's stuff or ship's flour was probably what was shipped west for common trade. It had a lot of "bran", and even if you use organic, whole wheat, pastry flour, for your hardtack... it's probably too nice as the modern millers packaging and selling the stuff think it's to be used for "pastry" ...,
So when I use flour for common bread, I use whole wheat pastry flour, but I add 1/4 to 1/3 of a cup of
whole wheat bran to it to simulate unbolted flour, THEN I measure out from that into to make my bread or ship's biscuit dough.
It does make a difference in texture and flavor..., and with all that fiber, you're not going to get bound-up under any circumstances.
Just thought I'd share :shocked2:
